I am having an issue with BM 3.7 authentication. I need to have a few users authenticate when open their internet connection because their is no client on their workstations. The issue I am having is that some users get the html form when they open up IE. For these guys it is easy to log in. However, other users get the pop-up login window and I cannot get these users to log in. We are running BM 3.7 with Service Pack 3.

Any help would be appreciated.
