Returns a set of temporary security credentials for users who have been authenticated via a SAML authentication response. This operation provides a mechanism for tying an enterprise identity store or directory to role-based AWS access without user-specific credentials or configuration.
The temporary security credentials returned by this operation consist of an access key ID, a secret access key, and a security token. Applications can use these temporary security credentials to sign calls to AWS services. The credentials are valid for the duration that you specified when calling AssumeRoleWithSAML
, which can be up to 3600 seconds (1 hour) or until the time specified in the SAML authentication response's NotOnOrAfter
value, whichever is shorter.
NOTE:The maximum duration for a session is 1 hour, and the minimum duration is 15 minutes, even if values outside this range are specified.
Optionally, you can pass an AWS IAM access policy to this operation. The temporary security credentials that are returned by the operation have the permissions that are associated with the access policy of the role being assumed, except for any permissions explicitly denied by the policy you pass. This gives you a way to further restrict the permissions for the federated user. These policies and any applicable resource-based policies are evaluated when calls to AWS are made using the temporary security credentials.
Before your application can call AssumeRoleWithSAML
, you must configure your SAML identity provider (IdP) to issue the claims required by AWS. Additionally, you must use AWS Identity and Access Management (AWS IAM) to create a SAML provider entity in your AWS account that represents your identity provider, and create an AWS IAM role that specifies this SAML provider in its trust policy.
Calling AssumeRoleWithSAML
does not require the use of AWS security credentials. The identity of the caller is validated by using keys in the metadata document that is uploaded for the SAML provider entity for your identity provider.
