login to imapd with local username is killing me

[Gavin McCullagh]

Hi,

having finally migrated to our new kolab setup and had to change everyone's
username from <username> to <username>@<domain>, I'm not getting lots of
confused users who are not following instructions and persisting with the
old <username>.  

They _should_ be unable to login.  Instead, they login, see no email and
presume we've lost all of their email in the transition.  This is described
in issue2869:
	https://issues.kolab.org/issue2869

Can anyone think of a workaround to block people from logging in with the
local username?  This is really causing us a lot of problems.

Gavin
