How will OAM SSO for Demantra, integrated with ASCP/EBS R12.2.3.

Folks,

We are implementing Demantra, 12.2.3 , also have ASCP/EBS R 12.2.3.

Our Enterprise SSO is OAM, Oracle Access Manager, 11gR2, this OAM is already been used as SSO for our source EBS, which is R 12.1.3, using WNA (Windows Native Authenication)/Kerberos.

From what high level I have read so far, my understanding is that:

A) we can integrate our existing OAM 11gR2, with ASCP/EBS R12.2.3  and then users once they are into ASCP , can click on a link to access Demantra apps.

Also I read,  I can directly integrate our existing OAM 11gR2, with Demantra, without doing the integration with the ASCP/EBS R12.2.3.
