A low-level client representing AWS Transfer Family
Amazon Web Services Transfer Family is a fully managed service that enables the transfer of files over the File Transfer Protocol (FTP), File Transfer Protocol over SSL (FTPS), or Secure Shell (SSH) File Transfer Protocol (SFTP) directly into and out of Amazon Simple Storage Service (Amazon S3). Amazon Web Services helps you seamlessly migrate your file transfer workflows to Amazon Web Services Transfer Family by integrating with existing authentication systems, and providing DNS routing with Amazon Route 53 so nothing changes for your customers and partners, or their applications. With your data in Amazon S3, you can use it with Amazon Web Services services for processing, analytics, machine learning, and archiving. Getting started with Amazon Web Services Transfer Family is easy since there is no infrastructure to buy and set up.
import boto3
client = boto3.client('transfer')
These are the available methods:
Check if an operation can be paginated.
Used by administrators to choose which groups in the directory should have access to upload and download files over the enabled protocols using Amazon Web Services Transfer Family. For example, a Microsoft Active Directory might contain 50,000 users, but only a small fraction might need the ability to transfer files to the server. An administrator can use CreateAccess to limit the access to the correct set of users who need this ability.

The landing directory (folder) for a user when they log in to the server using the client.
A HomeDirectory example is /bucket_name/home/mydirectory .
Logical directory mappings that specify what Amazon S3 or Amazon EFS paths and keys should be visible to your user and how you want to make them visible. You must specify the Entry and Target pair, where Entry shows how the path is made visible and Target is the actual Amazon S3 or Amazon EFS path. If you only specify a target, it is displayed as is. You also must ensure that your Amazon Web Services Identity and Access Management (IAM) role provides access to paths in Target . This value can only be set when HomeDirectoryType is set to LOGICAL .
The following is an Entry and Target pair example.
[ { "Entry": "/directory1", "Target": "/bucket_name/home/mydirectory" } ]
In most cases, you can use this value instead of the session policy to lock down your user to the designated home directory ("chroot "). To do this, you can set Entry to / and set Target to the HomeDirectory parameter value.
The following is an Entry and Target pair example for chroot .
[ { "Entry:": "/", "Target": "/bucket_name/home/mydirectory" } ]
Note
If the target of a logical directory entry does not exist in Amazon S3 or EFS, the entry is ignored. As a workaround, you can use the Amazon S3 API or EFS API to create 0 byte objects as place holders for your directory. If using the CLI, use the s3api or efsapi call instead of s3 or efs so you can use the put-object operation. For example, you use the following: aws s3api put-object --bucket bucketname --key path/to/folder/ . Make sure that the end of the key name ends in a / for it to be considered a folder.
Represents an object that contains entries and targets for HomeDirectoryMappings .
The following is an Entry and Target pair example for chroot .
[ { "Entry:": "/", "Target": "/bucket_name/home/mydirectory" } ]

Represents an entry for HomeDirectoryMappings .
Represents the map target that is used in a HomeDirectorymapEntry .
A session policy for your user so that you can use the same IAM role across multiple users. This policy scopes down user access to portions of their Amazon S3 bucket. Variables that you can use inside this policy include ${Transfer:UserName} , ${Transfer:HomeDirectory} , and ${Transfer:HomeBucket} .
Note
This only applies when the domain of ServerId is S3. EFS does not use session policies.
For session policies, Amazon Web Services Transfer Family stores the policy as a JSON blob, instead of the Amazon Resource Name (ARN) of the policy. You save the policy as a JSON blob and pass it in the Policy argument.
For an example of a session policy, see Example session policy .
For more information, see AssumeRole in the Amazon Web Services Security Token Service API Reference .
The full POSIX identity, including user ID (Uid ), group ID (Gid ), and any secondary groups IDs (SecondaryGids ), that controls your users' access to your Amazon EFS file systems. The POSIX permissions that are set on files and directories in your file system determine the level of access your users get when transferring files into and out of your Amazon EFS file systems.
The POSIX user ID used for all EFS operations by this user.
The POSIX group ID used for all EFS operations by this user.
The secondary POSIX group IDs used for all EFS operations by this user.
[REQUIRED]
Specifies the Amazon Resource Name (ARN) of the IAM role that controls your users' access to your Amazon S3 bucket or EFS file system. The policies attached to this role determine the level of access that you want to provide your users when transferring files into and out of your Amazon S3 bucket or EFS file system. The IAM role should also contain a trust relationship that allows the server to access your resources when servicing your users' transfer requests.
[REQUIRED]
A system-assigned unique identifier for a server instance. This is the specific server that you added your user to.
[REQUIRED]
A unique identifier that is required to identify specific groups within your directory. The users of the group that you associate have access to your Amazon S3 or Amazon EFS resources over the enabled protocols using Amazon Web Services Transfer Family. If you know the group name, you can view the SID values by running the following command using Windows PowerShell.
Get-ADGroup -Filter {samAccountName -like "*YourGroupName* *"} -Properties * | Select SamAccountName,ObjectSid
In that command, replace YourGroupName with the name of your Active Directory group.
The regex used to validate this parameter is a string of characters consisting of uppercase and lowercase alphanumeric characters with no spaces. You can also include underscores or any of the following characters: =,.@:/-

The Amazon Resource Name (ARN) of the Amazon Web Services Certificate Manager (ACM) certificate. Required when Protocols is set to FTPS .
To request a new public certificate, see Request a public certificate in the Amazon Web Services Certificate Manager User Guide .
To import an existing certificate into ACM, see Importing certificates into ACM in the Amazon Web Services Certificate Manager User Guide .
To request a private certificate to use FTPS through private IP addresses, see Request a private certificate in the Amazon Web Services Certificate Manager User Guide .
Certificates with the following cryptographic algorithms and key sizes are supported:
Note
The certificate must be a valid SSL/TLS X.509 version 3 certificate with FQDN or IP address specified and information about the issuer.
The domain of the storage system that is used for file transfers. There are two domains available: Amazon Simple Storage Service (Amazon S3) and Amazon Elastic File System (Amazon EFS). The default value is S3.
Note
After the server is created, the domain cannot be changed.
The virtual private cloud (VPC) endpoint settings that are configured for your server. When you host your endpoint within your VPC, you can make it accessible only to resources within your VPC, or you can attach Elastic IP addresses and make it accessible to clients over the internet. Your VPC's default security groups are automatically assigned to your endpoint.
A list of address allocation IDs that are required to attach an Elastic IP address to your server's endpoint.
Note
This property can only be set when EndpointType is set to VPC and it is only valid in the UpdateServer API.
A list of subnet IDs that are required to host your server endpoint in your VPC.
Note
This property can only be set when EndpointType is set to VPC .
The ID of the VPC endpoint.
Note
This property can only be set when EndpointType is set to VPC_ENDPOINT .
For more information, see https://docs.aws.amazon.com/transfer/latest/userguide/create-server-in-vpc.html#deprecate-vpc-endpoint.
The VPC ID of the VPC in which a server's endpoint will be hosted.
Note
This property can only be set when EndpointType is set to VPC .
A list of security groups IDs that are available to attach to your server's endpoint.
Note
This property can only be set when EndpointType is set to VPC .
You can edit the SecurityGroupIds property in the UpdateServer API only if you are changing the EndpointType from PUBLIC or VPC_ENDPOINT to VPC . To change security groups associated with your server's VPC endpoint after creation, use the Amazon EC2 ModifyVpcEndpoint API.
The type of endpoint that you want your server to use. You can choose to make your server's endpoint publicly accessible (PUBLIC) or host it inside your VPC. With an endpoint that is hosted in a VPC, you can restrict access to your server and resources only within your VPC or choose to make it internet facing by attaching Elastic IP addresses directly to it.
Note
After May 19, 2021, you won't be able to create a server using EndpointType=VPC_ENDPOINT in your Amazon Web Services account if your account hasn't already done so before May 19, 2021. If you have already created servers with EndpointType=VPC_ENDPOINT in your Amazon Web Services account on or before May 19, 2021, you will not be affected. After this date, use EndpointType =``VPC`` .
For more information, see https://docs.aws.amazon.com/transfer/latest/userguide/create-server-in-vpc.html#deprecate-vpc-endpoint.
It is recommended that you use VPC as the EndpointType . With this endpoint type, you have the option to directly associate up to three Elastic IPv4 addresses (BYO IP included) with your server's endpoint and use VPC security groups to restrict traffic by the client's public IP address. This is not possible with EndpointType set to VPC_ENDPOINT .
The RSA private key as generated by the ssh-keygen -N "" -m PEM -f my-new-server-key command.
Warning
If you aren't planning to migrate existing users from an existing SFTP-enabled server to a new server, don't update the host key. Accidentally changing a server's host key can be disruptive.
For more information, see Change the host key for your SFTP-enabled server in the Amazon Web Services Transfer Family User Guide .
Required when IdentityProviderType is set to AWS_DIRECTORY_SERVICE or API_GATEWAY . Accepts an array containing all of the information required to use a directory in AWS_DIRECTORY_SERVICE or invoke a customer-supplied authentication API, including the API Gateway URL. Not required when IdentityProviderType is set to SERVICE_MANAGED .
Provides the location of the service endpoint used to authenticate users.
Provides the type of InvocationRole used to authenticate the user account.
The identifier of the Amazon Web ServicesDirectory Service directory that you want to stop sharing.
The ARN for a lambda function to use for the Identity provider.
Specifies the mode of authentication for a server. The default value is SERVICE_MANAGED , which allows you to store and access user credentials within the Amazon Web Services Transfer Family service.
Use AWS_DIRECTORY_SERVICE to provide access to Active Directory groups in Amazon Web Services Managed Active Directory or Microsoft Active Directory in your on-premises environment or in Amazon Web Services using AD Connectors. This option also requires you to provide a Directory ID using the IdentityProviderDetails parameter.
Use the API_GATEWAY value to integrate with an identity provider of your choosing. The API_GATEWAY setting requires you to provide an API Gateway endpoint URL to call for authentication using the IdentityProviderDetails parameter.
Use the LAMBDA value to directly use a Lambda function as your identity provider. If you choose this value, you must specify the ARN for the lambda function in the Function parameter for the IdentityProviderDetails data type.
Specifies the file transfer protocol or protocols over which your file transfer protocol client can connect to your server's endpoint. The available protocols are:
Note
If you select FTPS , you must choose a certificate stored in Amazon Web Services Certificate Manager (ACM) which is used to identify your server when clients connect to it over FTPS.
If Protocol includes either FTP or FTPS , then the EndpointType must be VPC and the IdentityProviderType must be AWS_DIRECTORY_SERVICE or API_GATEWAY .
If Protocol includes FTP , then AddressAllocationIds cannot be associated.
If Protocol is set only to SFTP , the EndpointType can be set to PUBLIC and the IdentityProviderType can be set to SERVICE_MANAGED .
Key-value pairs that can be used to group and search for servers.
Creates a key-value pair for a specific resource. Tags are metadata that you can use to search for and group a resource for various purposes. You can apply tags to servers, users, and roles. A tag key can take more than one value. For example, to group servers for accounting purposes, you might create a tag called Group and assign the values Research and Accounting to that group.
The name assigned to the tag that you create.
Contains one or more values that you assigned to the key name you create.
Specifies the workflow ID for the workflow to assign and the execution role used for executing the workflow.
A trigger that starts a workflow: the workflow begins to execute after a file is uploaded.
Specifies the workflow ID for the workflow to assign and the execution role used for executing the workflow.
A unique identifier for the workflow.

(dict) --
ServerId (string) --
A system-assigned unique identifier for a server that has this access assigned.
Access (dict) --
The external ID of the server that the access is attached to.
HomeDirectory (string) --
The landing directory (folder) for a user when they log in to the server using the client.
A HomeDirectory example is /bucket_name/home/mydirectory .
HomeDirectoryMappings (list) --
Logical directory mappings that specify what Amazon S3 or Amazon EFS paths and keys should be visible to your user and how you want to make them visible. You must specify the Entry and Target pair, where Entry shows how the path is made visible and Target is the actual Amazon S3 or Amazon EFS path. If you only specify a target, it is displayed as is. You also must ensure that your Amazon Web Services Identity and Access Management (IAM) role provides access to paths in Target . This value can only be set when HomeDirectoryType is set to LOGICAL .
In most cases, you can use this value instead of the session policy to lock down the associated access to the designated home directory ("chroot "). To do this, you can set Entry to '/' and set Target to the HomeDirectory parameter value.
(dict) --
Represents an object that contains entries and targets for HomeDirectoryMappings .
The following is an Entry and Target pair example for chroot .
[ { "Entry:": "/", "Target": "/bucket_name/home/mydirectory" } ]
Note
If the target of a logical directory entry does not exist in Amazon S3 or EFS, the entry is ignored. As a workaround, you can use the Amazon S3 API or EFS API to create 0 byte objects as place holders for your directory. If using the CLI, use the s3api or efsapi call instead of s3 or efs so you can use the put-object operation. For example, you use the following: aws s3api put-object --bucket bucketname --key path/to/folder/ . Make sure that the end of the key name ends in a / for it to be considered a folder.
Entry (string) --
Represents an entry for HomeDirectoryMappings .
Target (string) --
Represents the map target that is used in a HomeDirectorymapEntry .
HomeDirectoryType (string) --
The type of landing directory (folder) you want your users' home directory to be when they log into the server. If you set it to PATH , the user will see the absolute Amazon S3 bucket or EFS paths as is in their file transfer protocol clients. If you set it LOGICAL , you need to provide mappings in the HomeDirectoryMappings for how you want to make Amazon S3 or EFS paths visible to your users.
Policy (string) --
A session policy for your user so that you can use the same IAM role across multiple users. This policy scopes down user access to portions of their Amazon S3 bucket. Variables that you can use inside this policy include ${Transfer:UserName} , ${Transfer:HomeDirectory} , and ${Transfer:HomeBucket} .
PosixProfile (dict) --
The full POSIX identity, including user ID (Uid ), group ID (Gid ), and any secondary groups IDs (SecondaryGids ), that controls your users' access to your Amazon EFS file systems. The POSIX permissions that are set on files and directories in your file system determine the level of access your users get when transferring files into and out of your Amazon EFS file systems.
Uid (integer) --
The POSIX user ID used for all EFS operations by this user.
Gid (integer) --
The POSIX group ID used for all EFS operations by this user.
SecondaryGids (list) --
The secondary POSIX group IDs used for all EFS operations by this user.
Role (string) --
Specifies the Amazon Resource Name (ARN) of the IAM role that controls your users' access to your Amazon S3 bucket or EFS file system. The policies attached to this role determine the level of access that you want to provide your users when transferring files into and out of your Amazon S3 bucket or EFS file system. The IAM role should also contain a trust relationship that allows the server to access your resources when servicing your users' transfer requests.
ExternalId (string) --
A unique identifier that is required to identify specific groups within your directory. The users of the group that you associate have access to your Amazon S3 or Amazon EFS resources over the enabled protocols using Amazon Web Services Transfer Family. If you know the group name, you can view the SID values by running the following command using Windows PowerShell.
Get-ADGroup -Filter {samAccountName -like "*YourGroupName* *"} -Properties * | Select SamAccountName,ObjectSid

The landing directory (folder) for a user when they log in to the server using the client.
A HomeDirectory example is /bucket_name/home/mydirectory .
Logical directory mappings that specify what Amazon S3 or Amazon EFS paths and keys should be visible to your user and how you want to make them visible. You must specify the Entry and Target pair, where Entry shows how the path is made visible and Target is the actual Amazon S3 or Amazon EFS path. If you only specify a target, it is displayed as is. You also must ensure that your Amazon Web Services Identity and Access Management (IAM) role provides access to paths in Target . This value can only be set when HomeDirectoryType is set to LOGICAL .
The following is an Entry and Target pair example.
[ { "Entry": "/directory1", "Target": "/bucket_name/home/mydirectory" } ]
In most cases, you can use this value instead of the session policy to lock down your user to the designated home directory ("chroot "). To do this, you can set Entry to / and set Target to the HomeDirectory parameter value.
The following is an Entry and Target pair example for chroot .
[ { "Entry:": "/", "Target": "/bucket_name/home/mydirectory" } ]
Note
If the target of a logical directory entry does not exist in Amazon S3 or EFS, the entry is ignored. As a workaround, you can use the Amazon S3 API or EFS API to create 0 byte objects as place holders for your directory. If using the CLI, use the s3api or efsapi call instead of s3 or efs so you can use the put-object operation. For example, you use the following: aws s3api put-object --bucket bucketname --key path/to/folder/ . Make sure that the end of the key name ends in a / for it to be considered a folder.
Represents an object that contains entries and targets for HomeDirectoryMappings .
The following is an Entry and Target pair example for chroot .
[ { "Entry:": "/", "Target": "/bucket_name/home/mydirectory" } ]
Note
If the target of a logical directory entry does not exist in Amazon S3 or EFS, the entry is ignored. As a workaround, you can use the Amazon S3 API or EFS API to create 0 byte objects as place holders for your directory. If using the CLI, use the s3api or efsapi call instead of s3 or efs so you can use the put-object operation. For example, you use the following: aws s3api put-object --bucket bucketname --key path/to/folder/ . Make sure that the end of the key name ends in a / for it to be considered a folder.
Represents an entry for HomeDirectoryMappings .
Represents the map target that is used in a HomeDirectorymapEntry .
A session policy for your user so that you can use the same IAM role across multiple users. This policy scopes down user access to portions of their Amazon S3 bucket. Variables that you can use inside this policy include ${Transfer:UserName} , ${Transfer:HomeDirectory} , and ${Transfer:HomeBucket} .
Note
This only applies when the domain of ServerId is S3. EFS does not use session policies.
For session policies, Amazon Web Services Transfer Family stores the policy as a JSON blob, instead of the Amazon Resource Name (ARN) of the policy. You save the policy as a JSON blob and pass it in the Policy argument.
For an example of a session policy, see Example session policy .
For more information, see AssumeRole in the Amazon Web ServicesSecurity Token Service API Reference .
The full POSIX identity, including user ID (Uid ), group ID (Gid ), and any secondary groups IDs (SecondaryGids ), that controls your users' access to your Amazon EFS file systems.

To import an existing certificate into ACM, see Importing certificates into ACM in the Amazon Web ServicesCertificate Manager User Guide .
To request a private certificate to use FTPS through private IP addresses, see Request a private certificate in the Amazon Web ServicesCertificate Manager User Guide .
Certificates with the following cryptographic algorithms and key sizes are supported:
Note
The certificate must be a valid SSL/TLS X.509 version 3 certificate with FQDN or IP address specified and information about the issuer.
The protocol settings that are configured for your server.
Use the PassiveIp parameter to indicate passive mode (for FTP and FTPS protocols). Enter a single dotted-quad IPv4 address, such as the external IP address of a firewall, router, or load balancer.
Indicates passive mode, for FTP and FTPS protocols. Enter a single dotted-quad IPv4 address, such as the external IP address of a firewall, router, or load balancer. For example:
``aws transfer update-server --protocol-details PassiveIp=*0.0.0.0* ``
Replace `` 0.0.0.0 `` in the example above with the actual IP address you want to use.
Note
If you change the PassiveIp value, you must stop and then restart your Transfer server for the change to take effect. For details on using Passive IP (PASV) in a NAT environment, see Configuring your FTPS server behind a firewall or NAT with Amazon Web Services Transfer Family .
The virtual private cloud (VPC) endpoint settings that are configured for your server. When you host your endpoint within your VPC, you can make it accessible only to resources within your VPC, or you can attach Elastic IP addresses and make it accessible to clients over the internet. Your VPC's default security groups are automatically assigned to your endpoint.
A list of address allocation IDs that are required to attach an Elastic IP address to your server's endpoint.
Note
This property can only be set when EndpointType is set to VPC and it is only valid in the UpdateServer API.
A list of subnet IDs that are required to host your server endpoint in your VPC.
Note
This property can only be set when EndpointType is set to VPC .
The ID of the VPC endpoint.
Note
This property can only be set when EndpointType is set to VPC_ENDPOINT .
For more information, see https://docs.aws.amazon.com/transfer/latest/userguide/create-server-in-vpc.html#deprecate-vpc-endpoint.
The VPC ID of the VPC in which a server's endpoint will be hosted.
Note
This property can only be set when EndpointType is set to VPC .
A list of security groups IDs that are available to attach to your server's endpoint.
Note
This property can only be set when EndpointType is set to VPC .
You can edit the SecurityGroupIds property in the UpdateServer API only if you are changing the EndpointType from PUBLIC or VPC_ENDPOINT to VPC . To change security groups associated with your server's VPC endpoint after creation, use the Amazon EC2 ModifyVpcEndpoint API.
The type of endpoint that you want your server to use. You can choose to make your server's endpoint publicly accessible (PUBLIC) or host it inside your VPC. With an endpoint that is hosted in a VPC, you can restrict access to your server and resources only within your VPC or choose to make it internet facing by attaching Elastic IP addresses directly to it.
Note
After May 19, 2021, you won't be able to create a server using EndpointType=VPC_ENDPOINT in your Amazon Web Servicesaccount if your account hasn't already done so before May 19, 2021. If you have already created servers with EndpointType=VPC_ENDPOINT in your Amazon Web Servicesaccount on or before May 19, 2021, you will not be affected. After this date, use EndpointType =``VPC`` .
For more information, see https://docs.aws.amazon.com/transfer/latest/userguide/create-server-in-vpc.html#deprecate-vpc-endpoint.
It is recommended that you use VPC as the EndpointType . With this endpoint type, you have the option to directly associate up to three Elastic IPv4 addresses (BYO IP included) with your server's endpoint and use VPC security groups to restrict traffic by the client's public IP address. This is not possible with EndpointType set to VPC_ENDPOINT .
The RSA private key as generated by ssh-keygen -N "" -m PEM -f my-new-server-key .
Warning
If you aren't planning to migrate existing users from an existing server to a new server, don't update the host key. Accidentally changing a server's host key can be disruptive.
For more information, see Change the host key for your SFTP-enabled server in the Amazon Web ServicesTransfer Family User Guide .
An array containing all of the information required to call a customer's authentication API method.
Provides the location of the service endpoint used to authenticate users.
Provides the type of InvocationRole used to authenticate the user account.
The identifier of the Amazon Web ServicesDirectory Service directory that you want to stop sharing.
The ARN for a lambda function to use for the Identity provider.
Specifies the file transfer protocol or protocols over which your file transfer protocol client can connect to your server's endpoint. The available protocols are:
Note
If you select FTPS , you must choose a certificate stored in Amazon Web ServicesCertificate Manager (ACM) which will be used to identify your server when clients connect to it over FTPS.
If Protocol includes either FTP or FTPS , then the EndpointType must be VPC and the IdentityProviderType must be AWS_DIRECTORY_SERVICE or API_GATEWAY .
If Protocol includes FTP , then AddressAllocationIds cannot be associated.
If Protocol is set only to SFTP , the EndpointType can be set to PUBLIC and the IdentityProviderType can be set to SERVICE_MANAGED .

)
The landing directory (folder) for a user when they log in to the server using the client.
A HomeDirectory example is /bucket_name/home/mydirectory .
Logical directory mappings that specify what Amazon S3 or Amazon EFS paths and keys should be visible to your user and how you want to make them visible. You must specify the Entry and Target pair, where Entry shows how the path is made visible and Target is the actual Amazon S3 or Amazon EFS path. If you only specify a target, it is displayed as is. You also must ensure that your Amazon Web Services Identity and Access Management (IAM) role provides access to paths in Target . This value can only be set when HomeDirectoryType is set to LOGICAL .
The following is an Entry and Target pair example.
[ { "Entry": "/directory1", "Target": "/bucket_name/home/mydirectory" } ]
In most cases, you can use this value instead of the session policy to lock down your user to the designated home directory ("chroot "). To do this, you can set Entry to '/' and set Target to the HomeDirectory parameter value.
The following is an Entry and Target pair example for chroot .
[ { "Entry:": "/", "Target": "/bucket_name/home/mydirectory" } ]
Note
If the target of a logical directory entry does not exist in Amazon S3 or EFS, the entry is ignored. As a workaround, you can use the Amazon S3 API or EFS API to create 0 byte objects as place holders for your directory. If using the CLI, use the s3api or efsapi call instead of s3 or efs so you can use the put-object operation. For example, you use the following: aws s3api put-object --bucket bucketname --key path/to/folder/ . Make sure that the end of the key name ends in a / for it to be considered a folder.
Represents an object that contains entries and targets for HomeDirectoryMappings .
The following is an Entry and Target pair example for chroot .
[ { "Entry:": "/", "Target": "/bucket_name/home/mydirectory" } ]

Represents an entry for HomeDirectoryMappings .
Represents the map target that is used in a HomeDirectorymapEntry .
A session policy for your user so that you can use the same IAM role across multiple users. This policy scopes down user access to portions of their Amazon S3 bucket. Variables that you can use inside this policy include ${Transfer:UserName} , ${Transfer:HomeDirectory} , and ${Transfer:HomeBucket} .
Note
This only applies when the domain of ServerId is S3. EFS does not use session policies.
For session policies, Amazon Web Services Transfer Family stores the policy as a JSON blob, instead of the Amazon Resource Name (ARN) of the policy. You save the policy as a JSON blob and pass it in the Policy argument.
For an example of a session policy, see Creating a session policy .
For more information, see AssumeRole in the Amazon Web Services Security Token Service API Reference .
Specifies the full POSIX identity, including user ID (Uid ), group ID (Gid ), and any secondary groups IDs (SecondaryGids ), that controls your users' access to your Amazon Elastic File Systems (Amazon EFS).
