Hi,

How to know if  EBS is registerd  in SSO OAM ?

Thank you.

There are ways , server side ways. But I m currently on a vacation and can't check it on a real system..

For now; look for the login page. If OAM is handling authentication, the standard EBS login page might be replaced by OAM's login portal.

Try logging in. If you're automatically logged into EBS after successful authentication on another application (without entering credentials again in EBS), it suggests SSO integration.
