ISA570W - Is there a way to apply different URL filtering for specific users or IP addresses?

[shumanick]

We are deploying the ISA570W and we have a use case that requires a group of about 7 people to only have access to a small subset of URLs that what the rest of our users have access to.  All of the users log into the same PCs and have static IP addresses assigned to them but are on the same subnet as the rest of our population.  Can I configure the ISA570W to limit ONLY THOSE USERS/PCs to access only a small set of URLs that we define?

Thank you,

Steve

I believe you can - simply great an access group, add the users to it, and block all categories/sites except for the ones you specifically whitelist.

I am just starting to look at it.  Is it Active Directory integrated for authentication?  Or do I have to create a separate user store for the users/groups that I would assign to specific access groups?  If it does support AD authentication, do you know if would take logged in credentials without a prompt when logged in and using IE for a browser?
