I am not using the correct protocol version (3?) and/or BaseDN? Is their a
way to get a listing not knowing the correct DC?


We were actually playing with this last night in our lab, and here is what we
found:

Using an LDAP Browser that we found called GQ (Requires GNOME and Linux)
(http://biot.com/gq/) - we were able to get a listing of the top level of the
Active Directory Tree: (no need to feed a base DN)

cn=Schema,cn=Configuration,dc=example,dc=com
cn=Configuration,dc=example,dc=com
dc=example,dc=com

This appears to be the extent of the anonymous browse capabilities (we only
played with it for a few hours, so YMMV)

If you are able to connect as the Administrator:

cn=Administrator,cn=Users,dc=example,dc=com

then you can enumerate the users, and all sorts of other fun things ;)

Users are under cn=Users,dc=example,dc=com
Computers are under cn=Computers,dc=example,dc=com

Anyways, hope this helps ;)
