MSCHAP? The guy is talking about MSCHAPv2....
Haven't seen PEAP-MSCHAP yet... :P
MSCHAPv2 needs plaint text or Microsoft NT style encrypted passwords. MSCHAPV2 uses md4 encryption.... does SQL support that? LDAP doesn't (MD5 and SHA).
PEAP machine authentication will only work in a Microsoft NT environment.
PEAP only supports inner EAP
TTLS support DIAMETER which can include:
PAP,CHAP and .... EAP.
There are two version of PEAP. MS PEAP and Cisco PEAP. MS PEAP works best with the MS IAS and Cisco PEAP works best with the ACS.
So everyone is doing their best as usuall...
