[Dovecot] Authentication problems

[R A]

Hi

This sounds to me like the failing Outlook clients might fall over to
CRAM-MD5
and you need to use the %m to map out the method sasl uses to return the
right
password.
Then you need to either use the source packet from ubuntu intrepid
and apply this patch

http://hg.dovecot.org/dovecot-1.1/rev/3fcfe8d316b6

Or download the release candidate of 1.1.3 

Also I use a sql query to get the password in the form:

password_query = SELECT id as user, passwd as password FROM passwds WHERE id = '%u' AND model = '%m'
