Invalid string supplied for user name

[Ben Hartmann <mail dot benhartmann at googlemail dot com>]

Hi there,
I've got a problem with the authentification to one of our
imap-servers. My username has the following format: "DOMAIN\user". But
imapsync come back with an errormessage saying: "Invalid string
supplied for user name".

Is there a way to get this working?


Here's the output of the imapsync-run (without usernames, pswd's, etc):
