As long as you provide the implementation of LoginProvider which you are, you can use the org.jboss.security.idm.UsernameAndPasswordLoginModule which ships with the Identity Manager component of the framework. Only thing you will need to do is get your JAAS configuration right.

The IdentityManager runs locally on each partner node of the application, but the implementation of your LoginProvider can connect to a remote data store/server where the Identity Credentials are stored. anonymous wrote : | the login methid in this case will be invokes at local server or central server | Technically the LoginProvider methods execute locally on each partner node, but their implementation is free to extract the actual data from a central data store...as per my explanation above. The whole idea behind an IdentityManager abstraction is so that it can hook in to other components of the SSO system like the Federation Server, Trust Server, JAAS modules etc without having to program to any proprietary API of an Identity system.
