If one has Supplicant (client) configured for EAP-PEAP w/ MS-CHAPv2 and on FreeRADIUS (or any other RADIUS server) configured to terminate PEAP w/MS_CHAPv2, but user profiles are stored on Active Directory.
Does FreeRADIUS support this ? If userprofile is on LDAP I think it would work since LDAP bind/search would return userPassword attribute, where as AD does not. Thus CHAP cannnot be done in AD case. Is this true ? Currently EAP-PEAP w/ MS-CHAPv2 termination works on some commercial FreeRADIUS servers who are running MS-Windows OS/kernel. As I understand in this case MS allows trusted domains to retrieve userPassword attribute from AD query, thus making CHAP to work. Is this right ? Can someone please comment and share some wisdom ? Alan.D: Any suggestions ?
