Hello, My network environment looks like the following: WinXP client --- Cisco Switch --- FreeRadius Server --- DC(Active Directory) I am able to authenticate the WinXP client with the local users file and EAP. Now I want FreeRadius to lookup the user credentials in Active Directory. I configured the LDAP modules and I am able to access Active directory for username lookup but the authentication fails because of the password that cannot be supplied in cleartext. The problem is, that I must use EAP because of 802.1X between the switch and the WinXP client. How can I solve this issue? I have read somewhere about how to modify FreeRadius source code in order to get EAP working with AD. I would appreciate a simpler solution. Any suggestion? Here is some output of radiusd: rlm_ldap: - authorize rlm_ldap: performing user authorization for pete radius_xlat: '(sAMAccountName=pete)' radius_xlat: 'cn=Users, dc=testdc' rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: performing search in cn=Users, dc=testdc, with filter (sAMAccountName=pete) rlm_ldap: looking for check items in directory... rlm_ldap: looking for reply items in directory... rlm_ldap: user pete authorized to use remote access rlm_ldap: ldap_release_conn: Release Id: 0 modcall[authorize]: module "ldap" returns ok for request 1 modcall: group authorize returns updated for request 1 rad_check_password: Found Auth-Type EAP auth: type "EAP" Processing the authenticate section of radiusd.conf modcall: entering group authenticate for request 1 rlm_eap: Request found, released from the list rlm_eap: EAP/md5 rlm_eap: processing type md5 rlm_eap_md5: User-Password is required for EAP-MD5 authentication rlm_eap: Handler failed in EAP/md5 rlm_eap: Failed in EAP select modcall[authenticate]: module "eap" returns invalid for request 1 modcall: group authenticate returns invalid for request 1 auth: Failed to validate the user.
