Yeah... Gave this a try and it didn't work out at all. Users either couldn't log in, or were constantly logged out and all sorts of strange things started happening with user accounts. Passwords would be working, then 5 mins later they wouldn't. Once I reset the password, they'd work for login, but then they couldn't login again until I set it again.
Not sure what's wrong and wish I had more info. I've pulled it and am exploring others, but I thought you should know. Thanx.
