About User Authentication

Siebel CRM supports the following mechanisms that the client uses to authentication 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.
• OAuth user using OAuth 2.0. For more information about OAuth 2.0, see About Configuring OAuth 2.0 for Authentication.
• 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.

Authentication parameters are configured in the Siebel Application Interface Profile.
