I've found that if I:

* create a new user account in the 'owner' group
* login as that new user
* delete the initial [email protected] user
* create a new 'owner' user with the username 'admin'
* login as this new 'admin'

Then I will get some very odd behaviors. In a nutshell, it seems having a username 'admin' is not a good idea. That should probably be in the "After install" documentation.

By odd behaviors, I mean for example that trying to add a new user will have all the fields populated with the 'admin' user info. Likewise, editing a user will have their data (in the form) replaced by the 'admin' info.

I haven't checked the code, but it seems highly likely that something is keying off the specific 'admin' username. It should not be.
