Gaah! Apologies for empty email preceding... Some thoughts on LoginManager and multiple UserSources... Here's LoginManager's getItem() method, which goes through the user sources, looking for an user with the right name: def getItem(self,name): # Retrieve a user with the given name, or None if no such # user exists. Uses the registry of UserSources, after # first checking for the superusSer/root users. if rootUsers.has_key(name): return rootUsers[name].__of__(self) for source in self.userSourcesList: user = source.__of__(self).getItem(name) if user is not None: return user return None This is called by a LoginMethod to retrieve a user object, which it then attempts to authenticate by calling the user object's authenticate() method. Now, what happens when you have multiple UserSources? getItem() returns the first user it finds. But it does this without attempting any authentication. So if you have two UserSources, both of which contain the same user, but for which the first won't authenticate, but the second will, you _don't_ get logged in (because getItem() just returns the first, which will fail, and the second doesn't get checked at all). Wouldn't it be "nice" if LoginManager could return multiple users from multiple sources, allowing the LoginMethod to try authenticating each, and decide for itself on whether to authenticate the user depending on the combination of results (eg you might want to authenticate provided at least one succeeds, or you might demand that they all succeed, etc.). Does this make sense to anyone else? Or am I being a complete nutcase? I should note that I don't (at this point) need this in any operational sense, I was just doing it for debugging purposes, but it strikes me that this would be an useful extension, and that one day I might well want it. Would this be a good thing? Would this be a waste of time? Is this an incredibly bad idea for some reason?
