802.1x Wireless User Auth w/ XP Mandatory Profiles?
Anyone ever had problems with 802.1x (EAP-MS-CHAPV2) user authentication over wireless not working when using mandatory user profiles (WinXP, SP3)?
When a user logs on with a mandatory profile the RADIUS server (IAS on 2008) just sees repeated attempts to authenticate, but there's never an IAS_SUCCESS event indicating a proper connection (the clients stall at the 'validating identity' stage). Simply changing the profile to a normal roaming profile (NTUSER.MAN --> NTUSER.DAT, no other changes) results in everything working fine with successful authentication, and connection, etc. Rather odd and rather frustrating - the lack of anything on Google makes me wonder if it mightn't be an SP3 foible, but annoyingly I don't have any SP2 machines immediately to hand...
Will crack out Wireshark/Process Monitor tomorrow and figure this out, but kind of hopeful someone here might well have experienced this before?
