I am integrating OBIEE 220.127.116.11 with OAM 11gR1 (18.104.22.168).
I have configured as per section 12.3 of following link:
After making all these configurtions, when i access:
http://<OHS server>:<OHS port>/analytics
User is getting prompted for auth from OAM. After successful auth, request gets redirected to WebLogic server hosting the OBIEE app. I have verified in OBI logs that the header value OAM_REMOTE_USER gets passed to OBI.
But even with all this, after successful OAM authentication, user is getting prompted with OBI login page.
