cyrus-imapd + sasl + ldap

[Rudy Gevaert]

Hello,

I have configured sasl 2.1.19 (the one that is in Debian) to use LDAP. 
This works as my gives an OK:

jura:/# testsaslauthd -u testuser1 at mail.ugent.be -p pass
0: OK "Success."

saslauthd[4147] :do_auth         : auth success: 
[user=testuser1 at mail.ugent.be] [service=imap] [realm=] [mech=ldap]
saslauthd[4147] :do_request      : response: OK

And this doesn't work.

jura:/# testsaslauthd -u testuser1 -r mail.ugent.be -p pass
0: NO "authentication failed

saslauthd[4145] :get_accept_lock : acquired accept lock
saslauthd[4147] :rel_accept_lock : released accept lock
saslauthd[4147] :do_auth         : auth failure: [user=testuser1] 
[service=imap] [realm=mail.ugent.be] [mech=ldap] [reason=Unknown]
saslauthd[4147] :do_request      : response: NO



I have configured cyrus-imapd's imapd.conf file with:
sasl_pwcheck_method: saslauthd
and
virtdomains: userid

I would now suspect that when login into the imap server, would work. 
But it doesn't.  I must have missed something.  E.g. I'm using mutt to 
access the mailbox: mutt -f imap://mail1.ugent.be
and enter testuser1 at mail.ugent.be als username.  This doesn't let me in. 
  I see in the logs from sasl:

saslauthd[4145] :rel_accept_lock : released accept lock
saslauthd[4146] :get_accept_lock : acquired accept lock
saslauthd[4145] :do_auth         : auth failure: [user=testuser1] 
[service=imap] [realm=mail.ugent.be] [mech=ldap] [reason=Unknown]
saslauthd[4145] :do_request      : response: NO

As debug output of case 2 and 3 is the same, I think they are the same 
problem.


What do I need to do to get this working?



Thanks in advance,

Rudy

PS I can't upgrade to the latest sasl to test the auxprop plugin because 
this isn't in Debian stable yet.
