Step 2: Configure the Enterprise IdP

You can configure parameters in the enterprise IdP to determine what information will be sent to Huawei Cloud. Huawei Cloud authenticates the federated identity and assigns permissions based on the received information.

If the SSO type is IAM user, the enterprise IdP must have the IAM_SAML_Attributes_xUserId assertion configured.
