This topic describes how to create a Resource Access Management (RAM) role for a trusted identity provider (IdP). This type of RAM role is used to implement role-based single sign-on (SSO) between Alibaba Cloud and a trusted IdP.

Prerequisites

An IdP is created.

Create a RAM role for a SAML IdP

To implement SAML 2.0-based SSO, you must create a RAM role for a SAML IdP.

  1. Log on to the RAM console by using your Alibaba Cloud account.
  2. In the left-side navigation pane, choose Identities > Roles.
  3. On the Roles page, click Create Role.
  4. In the Create Role panel, select IdP for Select Trusted Entity and click Next.
  5. Specify the RAM Role Name and Note parameters.
  6. Select SAML for IdP Type.
  7. Select a trusted IdP, read the conditions, and then click OK.
    Note Only the saml:recipient condition key is supported. This condition key is required and cannot be changed.
  8. Click Close.

Create a RAM role for an OIDC IdP

To implement OIDC-based SSO, you must create a RAM role for an OIDC IdP.

  1. Log on to the RAM console by using your Alibaba Cloud account.
  2. In the left-side navigation pane, choose Identities > Roles.
  3. On the Roles page, click Create Role.
  4. In the Create Role panel, select IdP for Select Trusted Entity and click Next.
  5. Specify the RAM Role Name and Note parameters.
  6. Select OIDC for IdP Type.
  7. Select a trusted IdP, specify the conditions in the Conditions section, and then click OK.
    The following table describes the supported conditions.
    Condition keyDescriptionRequiredExample
    oidc:issThe issuer. You can assume the RAM role only if the iss field of the OIDC token that you want to use to assume the RAM role meets this condition.

    The conditional operator must be StringEquals. The value must be the URL of the issuer that you specify for the selected OIDC IdP. You can specify this condition to ensure that you can use the OIDC token to assume the RAM role only if the OIDC token is issued by a trusted IdP.

    		Yeshttps://dev-xxxxxx.okta.com
    oidc:audThe audience. You can assume the RAM role only if the aud field of the OIDC token that you want to use to assume the RAM role meets this condition.

    The conditional operator must be StringEquals. The value can be one or more client IDs that you specify for the selected OIDC IdP. You can specify this condition to ensure that you can use the OIDC token to assume the RAM role only if the OIDC token is generated by using the client ID that you specify.

    		Yes0oa294vi1vJoClev****
    oidc:subThe subject. You can assume the RAM role only if the sub field of the OIDC token that you want to use to assume the RAM role meets this condition.

    The conditional operator can be a string of all types. The value can be up to 10 subjects. You can specify this condition to further limit the identity that you can use to assume the RAM role. You can also leave this condition unspecified.

What to do next

After a RAM role is created, the RAM role has no permissions. You can grant permissions to the RAM role. For more information, see Grant permissions to a RAM role.
