AD across both DMZ & LAN

["Leon North" <leon_nc () linuxmail org>]

Hi,

We currently have an NT4 domain in the DMZ and an unrelated NT4 domain internally. The DMZ domain contains a server 
running citrix, and is used for internet web browsing/email, so that we only have to allow the citrix connection 
through the FW to the LAN & no internal users can directly access the internet from their PC's.

As part of an upgrade to Active Directory (both domains Win2k3), we would like to get the DMZ to trust the internal 
domain, so that we only have one set of user accounts to manage. But I am not sure about a couple of things with this 
setup-

1. Will this work like this, so that we only need 1 user account per user instead of a seperate one externally to 
internally? (excuse the vagueness of the question)

2. If so, is that (not ideal I know but) an acceptable approach security wise, when the DMZ DC can access the accounts 
on the internal domain?

3. Can we configure it somehow so that the user gets a different profile when logging in to the DMZ only? I ask that 
because one potential issue I see is getting a virus infection into user profile while logged into the DMZ, then 
logging into an internal server.

Thanks for any help.

Leon
