LDAP Query Distinct

Hi, is it possible to only list distinct values with an LDAP query? I am getting duplicates of users for some reason but I only want them to be reported once, thank you for your help.

From stackoverflow

• Linq to Active Directory might help you here:

• I would be more concerned about why an LDAP query is returning users more than once, unless they exist more than once. That would seem to indicate a real issue in your LDAP source.

  That pretty much should not be happening.
