Siebel Single-Sign-On with OAuth2.0 or SAML

Hi,

Our enviroment: Siebel IP2016 and IBM Secure Identity Manager (as SSO Provider).

We are going to implement Web SSO for Siebel. We found several methods:

1) usual way with Web Proxy + special header

2) authentication with OAuth2.0   http://docs.oracle.com/cd/E74890_01/books/RestAPI/RestAPI_Overview13.html#wp1014806

3) authentication with SAML    http://docs.oracle.com/cd/E74890_01/books/Secur/secur_ssoauth014.htm

For the first method we found good instructions in Doc ID 1509084.1

For the second and the third methods we found nothing with detail instructions (just common descriptions).

So we want to understand:

• whether we can use OAuth2.0 or SAML for Web SSO or not?
