Query AD from DMZ via LDAP?

Tech-Archive recommends: Fix windows errors by optimizing your registry




I have an application that sits in our DMZ that needs to query our
internal AD domain. I'd like to keep things as secure as possible. I
tried configuring a new domain in the DMZ in a sperate forest,
creating a one way trust, but I am unable to use LDAP to locate the
internal domain user from the DMZ domain.

The next step I thought I would try is to use ADAM. Would this be a
viable solution (using the proxy class)? My requirements are that I
can simply use LDAP (in the DMZ) to authenticate a user in our
internal AD domain. Determining group memberships would be a bonus.

Thanks for any ideas.
