Cyrus using sasldb2, saslpasswd domain appending

[Pieter Berlijn]

I am currently in the process of setting up a Cyrus mailserver. I am
using auxprop as a pw_check method. I find that the saslpasswd2
utility appends my hostname to a specific username when I list the
users. No problems so far.

However, when I try to authenticate to my mailserver, Cyrus seems to
strip off this hostname when feeding it through IMAP login, telling me
the user does not exist. I am finding myself in the situation where
Cyrus cannot authenticate users that have my hostname added to them,
and saslpasswd2 being unable to create a user without the hostname
appended to it.

Am I overlooking something here?
