I can get you my SASL config from my test environment when I get to the office.  One thing to keep in mind, is that you MUST do an authenticated bind to AD, you cannot do anonymous bind, so you have to have a service account setup to allow SASL to authenticate to AD.  It can be the most basic user account, just has to be able to log into AD.

The log says that the entry is not found (nentries=0) either because
it does not exist, either because you can't read it (ACL).

But what are you using localhost behind your SASL pass trough? Seems
like you are doing a loop on your LDAP server.
