About User Authentication

Siebel CRM supports the following mechanisms that the client uses to authenticate user credentials:

  • Basic authentication over SSL. This is User ID and Password based authentication. The Base64 encoded value of the User ID and Password must be included in the Authorization header.

  • SSO, which can be either:

    • Pre-existing SSO mechanisms used for Siebel Applications or EAI.

    • SAML based SSO mechanisms. This is Identity Provider-Initiated Single Sign-On Authentication. For more information, see Siebel Security Guide.

  • OAuth user using OAuth 2.0. For more information about OAuth 2.0, see Siebel Security Guide.

Authentication parameters are configured in the Siebel Application Interface Profile. For information about REST Inbound Authentication parameters, see Configuring REST Inbound Authentication Parameters.
