How should I deploy my Barracuda Web Filter in an environment where users proxy through a Microsoft ISA server utilizing Integrated Windows Authentication?

Solution #00003407

Scope:
All Barracuda Web Filters in use with a Microsoft ISA proxy server, all firmware versions.

Answer:
Deploy the Barracuda Web Filter inline between the ISA server and the Internet, allowing workstations to authenticate with the Integrated Windows Authentication scheme (or any other scheme besides 'Basic') normally. Putting the Web Filter between the workstations and the ISA server would disrupt the authentication process and potentially prevent users from authenticating with the ISA, thereby preventing Internet access.
