Hi all, A while ago I did a few tests to see why single signon was breaking through cache peers. It seems like a valid single signon request comes with a DOMAIN\user format, and no domain once its passed through the peers - causing it to fail? I did it a long time ago and didn't really do enough work to know for sure but I do know it doesn't work. Can anyone suggest a way to get this to work, or is it even possible? Even just adding on the domain? Although I'm sure its not that simple.. We'd be willing to pay for the development work, and release it to the public - I just want to know if its possible? Thanks Dave
