Hello,
On my CentOS 4.4 machines I use saslpasswd2 to create
users.  Your maillog seems to indicate it is looking
for something in /etc/sasldb2.  What do you get from
the command sasldblistusers2?
Perhaps you need to recreate the userlist using
saslpasswd2 if you did not use that the first go
'round.

hth,
Brett
