I have been trying to find ways to enable single sign-on between WebCenter Spaces and custom portals. Without using OAM or OID.
I tried using SAML to simulate SSO. This hit a road-block because I couldn’t find a way to make ADFAuthentication work with SAML. The only configuration that allowed auto-login to work left the user with a blank screen (as it involved using /adfAuthentication as the destination target).
The only other way forward is to use a 3rd party SSO platform (JOSSO) for e.g. and see if WebCenter can be configured to work with it. I don’t have very high hopes for this. Oracle’s documentation limits itself to OID/OAM as the SSO provider and does not even mention the possibility of using a 3rd party SSO solution.
Have you had any successes (or failures) in this area? I would love to hear of how your attempts went.
