Hey, I need a bit of assistance. Brief summary: I have two RADIUS servers connected to different Active Directory domains. I got through the basic setup, EAP-PEAP / MSCHAP were working successfully authenticating against both domains. Then: - I upgraded freeradius on both from 2.1.10 to 2.2.0. - I generated new 'production' certificates on both servers. Now one of them is broken. Broken to the point where I can't even get eapol_test to run with success (though ntlm_auth still authenticates against AD properly). Since I was getting the "EAP session for state 0x56783e8f517027f8 did not finish!" error, I figured I messed something up badly with my new certs, so I blew away my /etc/freeradius directory, reinstalled freeradius 2.2.0 again and started from the ground up (it recreated the default certs). Still the same problem. The other box is working flawlessly with 2.2.0 and 'production' certs.

From Server: $ eapol_test -c peap-mschapv2.conf -s XXXXXXX

Please read http://wiki.freeradius.org/Certificate_Compatibility Thu Nov 8 11:26:22 2012 : Debug: WARNING: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Things I've already checked: - eap.conf is identical on both servers (I copied it over). - There were some old discussions about a Samba bug, but both servers are running 3.5.6. - radtest with PAP / users file is still working successfully. Can someone point me in the right direction? Where should I be looking? Is something lingering from my certificates failure or is the problem elsewhere? Thanks in advance, Jordan
