By the way, I tested the ldap auxprop plugin and it does not work for 
Cyrus-imap 2.2.2 cvs.
The funny thing is that with the same setup (minus the "sasl_" in 
imapd.conf) I can
authenticate with Postfix. Anyone had any success with that ? I know is 
more like a cyrus-sasl
problem, but as I said Postfix works in the same scenario.
