Within the last few months we updated our Websense 7.5 to the Websense AP-WEB 8.1. I'm unsure if this is when this started happening as it was just reported today. Under Policy Management > Clients, we have several users setup within the Directory as having a Policy assigned to them. We have found this simply doesn't enforce any sort of policy. I have tried modifying existing users, have tried a new user, and multiple different policies to no avail. Its almost as if Websense doesn't have a proper connection to AD to detect when a user is logging into a computer. Within this same window, if I put in the computers IP address, filtering works properly, so I know for sure that much is fine. Its just based on the AD user that isn't working.
I did check under Settings > Directory Services what we have setup, and its currently on "Windows Active Directory (Mixed Mode). From what I could find, with it setup this way there is no other additional configuration required.
In addition, if I click on the "Test Filtering" button on the right side, put in my user account and website I know is blocked, it does pop up a message saying, "Result:This URL was blocked. It does not appear in the current limited access filter."
I'm curious if I can attempt to establish if there is a proper AD connection or not, or some other troubleshooting idea you may have.
