You can call the AssumeRoleWithSAML operation to obtain a temporary identity to assume a RAM role during role-based single sign-on (SSO). This topic provides the log of a sample event in which a user of an enterprise assumed a RAM role during role-based SSO. This topic also describes the key fields involved in the event log.

Example

In the following example, a user named Alice@example.com assumed the testrole RAM role within the Alibaba Cloud account whose ID is 159498693826**** at 14:05:20 on August 2, 2021, UTC+8.

The sample event log contains the following key fields:

  • userIdentity.accountId: the ID of the Alibaba Cloud account to which the RAM role belongs. The value in this example is 159498693826****.
  • userIdentity.type: the identity type of the requester. The value in this example is saml-user, which indicates a user of an enterprise.
  • userIdentity.userName: the username of the requester. The value in this example is Alice@example.com, which indicates the username of the requester that assumed the RAM role.
  • eventName: the name of the event. The value in this example is AssumeRoleWithSAML, which indicates the operation to obtain a temporary identity to assume the RAM role.
  • SAMLProviderArn: the Alibaba Cloud Resource Name (ARN) of the identity provider (IdP)configured in the RAM console. The value is in the format of acs:ram::<account_ID>:saml-provider/<saml_provider_ID>. account_ID indicates the ID of the Alibaba Cloud account. saml_provider_ID indicates the name of the IdP. The value in this example is acs:ram::159498693826****:saml-provider/test. 159498693826**** indicates the ID of the Alibaba Cloud account. test indicates the name of the IdP.
  • RoleArn: the ARN of the RAM role assumed by the requester. The value is in the format of acs:ram::<accountID>:role/<roleName>. account_ID indicates the ID of the Alibaba Cloud account. roleName indicates the name of the RAM role assumed by the requester. The value in this example is acs:ram::159498693826****:role/testrole. 159498693826**** indicates the ID of the Alibaba Account. testrole indicates the name of the RAM role assumed by the requester.
  • AssumedRoleUser: the temporary identity used by the requester to assume the RAM role. The value in this example is {"Arn": "acs:ram::159498693826****:role/testrole/Alice","AssumedRoleId": "179432153826****:Alice"} . acs:ram::159498693826****:role/testrole/Alice indicates the ARN of the temporary identity. 179432153826****:Alice indicates the ID of the temporary identity.
  • Credentials: the access credential used by the requester to log on to the Alibaba Cloud Management Console. The value in this example is {"AccessKeyId": "STS.NUQNP4PiGyckMsNiGELCs****","AccessKeySecret": "Ss7sq2j0ZoJujZnmVgXcu6QT9e****","Expiration": "2021-08-02T07:05:20Z"} . STS.NUQNP4PiGyckMsNiGELCs**** indicates the AccessKey ID. Ss7sq2j0ZoJujZnmVgXcu6QT9e**** indicates the AccessKey secret. 2021-08-02T07:05:20Z indicates the point in time when the access credential expired.
  • referencedResources: the resource that is required to assume the RAM role. The value in this example is { "ACS::RAM::AccessKey": [ "STS.NUQNP4PiGyckMsNiGELCs****"]}, which indicates the temporary AccessKey secret obtained by the requester.
  • eventTime: the time when the event occurred in UTC. The value in this example is 2021-08-02T06:05:20Z, which indicates that the event occurred at 14:05:20 on August 2, 2021, UTC+8.
