How to setup Authentication against my Domain for my Secure SMTP Relay running on my ISA Firewall box.
Posted on 2004-10-11
Hope this is possible...
I have a secure authenticated SMTP relay running on my ISA 2000 firewall box. This is a W2K Server with IIS 5.0 SMTP services and is a stand alone server located in my perimeter network (same subnet but is not part of my Domain).
When I am outside of my network, I authenticate against the SMTP relay ONLY IF the User Account exists on the stand alone server (ISA Box). Then the relay forwards mail appropriately.
Obviously, I do not want to maintain users and passwords both on the ISA 2000 box and in the Domain, but want the users to authenticate against my domain AD.
I have been unfruitful thus far in figuring out how to accomplish this.
Anyone have any suggestions or guidance?
Thanks in advance,
