Reverse Proxy and Authentication - 24.Feb.2008 9:09:16 AM

I have configured the ISA server 2006 as a Reverse Proxy.

Here is the architecture :

Internal (IIS) -> ISA Server 2006 (with 3 Leg Perimeter) -> External

In the internal machine, i have configured Dynamics CRM 4.0 with Integrated
Windows Authentication

After configuring a Web Publishing Rule in the ISA Server 2006, the computer
in the external network can access the IIS by pointing to the ISA 2006.

I have an issue, that multiple IE User Login prompt is appeared. It's
supposed to be appeared only one time, but it appears every time.

I have captured the log information from the log file and it appears that
the connection is using the ISA\administrator (local workgroup administrator
login) instead of the login that i have supplied through IE window.

For your information, the ISA is not part of the domain inside the Internal.
The Web Listener is configured with Integrated Windows Authentication and
"allow client authentication over http" is also configured.

in the web publishing rule, i have configured "No delegation, but client may
authenticate directly"

Please let me know some guidance in how to resolve this issue.

Thanks for your help.
