[Dovecot] trouble getting digest-md5 & ldap working

[Udo Rader]

hi,

I am trying to set up dovecot with digest-md5 as authentication mechanism and
openldap as passdb.

My problem is ... that I just can't get it working. PLAIN authentication works
as expected, but no luck with digest-md5.

An excerpt from the two configuration files:

dovecot.conf:
--------CUT--------
auth = default
auth_mechanisms = plain digest-md5
auth_userdb = ldap /etc/dovecot/dovecot-ldap.conf
auth_passdb = ldap /etc/dovecot/dovecot-ldap.conf
--------CUT--------

dovecot-ldap.conf:
--------CUT--------
user_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%n)))
pass_filter = (&(objectClass=posixAccount)(|(mail=%u)(uid=%n)))
default_pass_scheme = plain
--------CUT--------

My dovecot installation with plain authentication and OpenLDAP has been quite
mature for a long time, so I doubt that it is an issue with openldap.

>From Cryrus-SASL I know that in order to get DIGEST-MD5 running it is required
to have plaintext passwords in the DIT, but that does not solve anything.

syslog tells me this:

dovecot-auth: May 08 21:25:09 Error: ldap(frodo): No password in reply

So any ideas on where I went wrong?
