Hi Ron,

I didn't had the time to check all logs but the error log. First thing you should check if there are LDAP REFFERALS enabled in the systems ldap.conf. I had a similar looking issue and it took me a good amount of time to figure out that I had to disable LDAP REFFERALS globally. This happened when using an AD as LDAP backend, but also applies to Samba4 as you can see in the following mailing list thread:

http://dovecot.markmail.org/message/mjurv4fp4w65u2ib?q=Dovecot+LDA+LDAP+look...

The settings within the systems ldap.conf might influence dovecot, because libldap (openldap) functions might read the global ldap.conf settings.

Hope that helps.

Cheers, Chris
