New issue 232: Don't disallow usernames with an @ character

Glenn Matthys:

Our SSO system works using email addresses as username, and with container auth Kallithea will create the user, but if you want to change any properties of that user afterwards, it errors out with "Username may only contain alphanumeric characters underscores, periods or dashes and must begin with an alphanumeric character or underscore".

Maybe this restriction could be lessened to allow email addresses? Or at the very least don't allow the creation of invalid usernames through container auth?
