OAM 11g SSO Not Working Between 2 Applications with 2 Different Login Forms

(Doc ID 1435454.1)

Last updated on FEBRUARY 02, 2017

Applies to:

Oracle Access Manager - Version 11.1.1.5.0 and later
Information in this document applies to any platform.

Symptoms


You have an environment with 2 applications (say, EBS and WebCenter) each protected under separate App Domains, each with its own login form. You could log into each app individually just fine, but if you log into one, SSO doesn't work into the other.

Ex:
- Login to EBS using EBS login form. This is expected (OK).
- Access WebCenter. You are presented with WebCenter login form. This is not expected as you already login via EBS (NOT OK).

EX:
- If you switch the Authentication so both Apps use the same login form, SSO works as expected (no matter which form is used).
