Hello List,
I'm trying to set up freeradius for users to authenticate against Active
Directory. The problem is that it seems to be that the client tries and
somehow succeeds but then it sends Access-Challenge again.
ntlm_auth from commandline works fine. If someone could pls take a look at
it, and point me to the problem source.
