Cyrus-SASL starts a query to your auxprop-database with $username and $realm. 
The $realm is equal with your servername or if configured with $servername 
in /etc/imapd.conf. If there is no dataset equal to both, you will see "user 
not found". Check your sasldblistusers on the Backend-Server if the Username 
and Realm is equal. I would guess the realm is wrong. Change your servername 
in imapd.conf to $realm to satisfy sasl.

username at realm userPassword
