Have anyone had problems with Exhange 2003 servers trying to use sasl
against Postfix+Dovecot SASL using the AUTH LOGIN Mechanism ?
I've done some smtp debugging, and it seems that Exchange sends the
usename at the same time as AUTH LOGIN i.e:
AUTH LOGIN <base64_username>
It then expects to be able to send the password.
mech-login.c silently discards all data after AUTH LOGIN and just
prompts the username prompt whetever the username has already been
supplied during initial AUTH LOGIN request.
I've attached a patch to make mech-login.c check if additional data
has been sent along with AUTH LOGIN, and in this case skip ahead
directly to the Password: prompt.
