Freeradius and AD

20 Apr 2010


      Hi,
I have a problem with authenticating users against an AD.
I'm connecting to a WPA2-Ent with PEAP and MS-CHAPv2
But it wont just work.
Any ideas?

freeradius is running in "SUSE enterprise 11-64bit"
Here is the output from "radiusd -f -X" (the relative parts)
