ACMPCA / Client / put_policy



Attaches a resource-based policy to a private CA.

A policy can also be applied by sharing a private CA through Amazon Web Services Resource Access Manager (RAM). For more information, see Attach a Policy for Cross-Account Access.

The policy can be displayed with GetPolicy and removed with DeletePolicy.

About Policies

  • A policy grants access on a private CA to an Amazon Web Services customer account, to Amazon Web Services Organizations, or to an Amazon Web Services Organizations unit. Policies are under the control of a CA administrator. For more information, see Using a Resource Based Policy with Amazon Web Services Private CA.

  • A policy permits a user of Certificate Manager (ACM) to issue ACM certificates signed by a CA in another account.

  • For ACM to manage automatic renewal of these certificates, the ACM user must configure a Service Linked Role (SLR). The SLR allows the ACM service to assume the identity of the user, subject to confirmation against the Amazon Web Services Private CA policy. For more information, see Using a Service Linked Role with ACM.

  • Updates made in Amazon Web Services Resource Manager (RAM) are reflected in policies. For more information, see Attach a Policy for Cross-Account Access.
