Without wishing to be a trouble maker, I don't particularly agree this is
low priority.

We're moving from an old Kolab v1 server which didn't do multiple domains
in a coherent way.  Our users currently have <firstname>.<surname> as their
username (using postfix/virtual for some non-default domain mapping). We
now need them to change their username to <firstname>.<surname>@<domain>
both in logging into kolab and cyrus.

We will of course be telling everyone, but if people don't get a "login
failed" from the old username, that is likely to cause us considerable
confusion.

Does anyone know of a workaround which will prevent this?
