Many of my customers use Google Apps. The main admin account for the various domains is monitored by my company in case someone uses that instead of our normal email or GTalk address. All of the companies are similar in setup:
I can register on of these to map to may login just fine and everything works as expected. But when I try to add the second company, it will overwrite the first. It’s as though I can only have one registration per user per service.
I don’t know if this is a bug or by design, but I though I would start here to find out. What I would like is to have multiple registrations for a single server map to a single user.
