Authentication Option on Applications on Websphere Application Server

Hi All,

We have an J2EE application siting on top of WAS v7 . Global security is configured for federated repository with Active Directory being one of the repository . However with the dynamic nature of the organization, the plan is to expand the repository by adding more repositories into the Federated repository. So there are chances the user id (uid) could be duplicate, i.e. same user X may reside in repository A & B. This will be a problem if both A & B are added to the repository and user X tries to login .

However , we want to provide an option like county/uid i.e. us/X or ca/X as a login id . Is that an option or there is some way we can map additional LDAP attributes to federated repository properties as login parameter while logging in ?

Any inputs will be greatly appreciated

Thanks,
Ramesh
