Follow the steps in this section to configure RSA Cloud Authentication Service as an SSO Agent SAML IdP to Amazon AWS.

Procedure

1. Logon to the RSA Cloud Administration Console and browse to Applications > Application Catalog, search for Amazon Web Services (AWS) and click +Add to add the connector.

2. Enter a name for the application in the Name field on the Basic Information page and click the Next Step button.

For second attribute, select Attribute Source as Constant, give the attribute name as https://aws.amazon.com/SAML/Attributes/Role and provide its value in Property as comma separated values of The ARN of a role that the user can be mapped to, The ARN of the SAML provider. In this example, value is given as arn:aws:iam::380329356478:role/blrPE-role1,arn:aws:iam::380329356478:saml-provider/blrPE.

Note:  If the values for Role ARN and Provider ARN are not known, enter placeholder values <RoleARN>,<ProviderARN> in the Property field to continue with the configuration. The actual value will be entered after completing the configuration of Amazon AWS as the SP.

11. Scroll down to the Uncommon Formatting SAML Response Options section. Under Sign Outgoing Assertion, select Assertion within Response.
