Mohib, the link you provided in the response is helpful and may be part of the solution we are looking for, but what I am really looking for is a way to configure Gluu to read from different user repoos and construct a token full of claims that are aggregated from multiple user repos. I realize this may not be possible because how would Gluu know that user1 in user repo1 is in any way related to user1 in repo2. Gluu would have to know the two users are linked before it could even attempt to aggregate attributes from both into claims for a token. Any further insight you can provide into dealing with this type of solution would be helpful.
