Hi umeli. I believe the use of "domain??sub?" in the related question were just placeholders for the actual domain names. I don't see any reference to question marks in any available LDAP documentation.

Found the solution to what I was looking for. Turns out you do need to specify a specific domain controller by its DNS entry, and I didn’t realize I had to include the FQDN in the connection string. The working query was:

Just trying to assign an assist to jwilleke since the info was good but lacked the necessary syntax for the VAMT.

jwilleke provided accurate information for an LDAP query, then I posted the solution for plugging it into the VAMT.
