Hi I'm working on 802.1x implementation(cisco 2950, freeradius, ldap), i face a problem. First of all, defining users and passwords in users file in raddb works well with md5 authentication. Then i tried to use ldap, then with radtest i get accept-accept packet. But while authenticating from xp client with md5-challenge, I got Auth:rlm_ldap:Attribute "User-Password" is required for authentication error. In one of the e-mail you said don't authenticate from ldap, but with radtest function i get success!!! The passwords are kept clear text. I'm looking forward to getting your help. I also send radius debug log.
