I have made some more progress (of a sort).

I added another Python Method to the LoginManager called user_names :


Parameter list:

self

Body:

return self.getUserNames()


As far as i can see, this should be functionally equivalent to the
user_names method in User.py:

    def user_names(self):
        return self.getUserNames()


But it doesn't work. On the bright side, I've managed to break the
manage_listLocalRoles local roles screen. This is the first time that
I've had any interaction with the local roles screen, so I guess now I
now I'm messing with the right stuff.

The error message I get is:

Error Type: AttributeError
Error Value: __hash__

Here is the traceback:

Any ideas?
