> Clément,
> After finding your SASL delegation article (http://ltb-project.org/wiki/documentation/general/sasl_delegation), I have been trying to configure SASL against multiple domains (Active Directory) via OpenLDAP.  After getting the first examples working correctly, I am struggling to get the configuration for several LDAP directories - with OpenLDAP ldap backend working.  This is the configuration that I need to implement.  After searching the internet for several days, I was hoping that you could potentially provide some direction as I am lost right now.
> Interestingly, the error message in /var/log/messages show service=imap when testing with testsaslauthd; however, I expect that it should be service=ldap.  Below is the complete error message:
> Nov 27 15:21:36 pabeldapd01 saslauthd[18311]: do_auth         : auth failure: [user=user1] [service=imap] [realm=] [mech=ldap] [reason=Unknown]
> Any suggestions?  I can provide the conf files if that will help.
> Your article is very helpful.  I am likely missing something simple as this is my first time working with SASL so I would greatly appreciate any assistance.
> Thanks,

Hi Daniel,

you should post such question on the mailing list.

You should check your saslauthd configuration with testsaslauthd
command, and monitor OpenLDAP log to see how LDAP requests are done.
