RE: Active Directory user enumeration



The default behavior was changed in 2003. 2000 generally allowed
anonymous connections and then the results were based on the individual
objects' permissions. By default, anonymous LDAP operations, except
rootDSE searches and binds, are not permitted on Windows 2003 domain
controllers, any other query will result in domain controller requesting
authenticated bind to LDAP.

Anonymous LDAP operations to Active Directory are disabled on Windows
Server 2003 domain controllers:

I'm not sure there is a way to enumerate AD through LDAP without
having to authenticate first. I have not tried it, but I am guessing
that Anonymous Bind is turned off by default (man, now I'm kinda
paranoid, I'll have to check!)
