Siebel Authentication via redirecting users to ADFS Identity Management Tool

Hi,

We were exploring few options to allow Single Sign on for our 3rd party Call center agents. However, since these agents login into Siebel from their own company domain (their m/cs are not in our domain), the OOTB single sign on option isn't feasible. So, a solution approach as below was proposed to us, through ADFS:

1. Agent hits the Siebel URL. This redirects the request to ADFS Identity Manager Login page (which is different than Siebel login page).

2. Agent then submits his credentials on ADFS login page, which authenticates the user and creates a session cookie, which is used by Siebel Application for authentication. As a result, user automatically gets logged into Siebel application.
