Hi Sorry for too many mails. Problem solved by setting identity and password in radius.conf with proper user in ldap. I managed to get User-Password from ldap at the end as shown below. rlm_ldap: Added password ramazan in check items rlm_ldap: looking for check items in directory... rlm_ldap: Adding userpassword as User-Password, value ramazan & op=21 rlm_ldap: looking for reply items in directory... rlm_ldap: Adding radiusTunnelPrivateGroupId as Tunnel-Private-Group-Id, value 2 & op=11 rlm_ldap: Adding radiusTunnelMediumType as Tunnel-Medium-Type, value 6 & op=11 rlm_ldap: Adding radiusTunnelType as Tunnel-Type, value VLAN & op=11 rlm_ldap: Adding radiusClass as Class, value employee & op=11 rlm_ldap: user ramazan authorized to use remote access rlm_ldap: ldap_release_conn: Release Id: 0 modcall[authorize]: module "ldap" returns ok for request 1 modcall: leaving 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: Freeing handler modcall[authenticate]: module "eap" returns ok for request 1 modcall: leaving group authenticate (returns ok) for request 1 Login OK: [ramazan/<no User-Password attribute>] (from client ldapsrv port 50001 cli 00-12-79-AE-D2-4D) On 1/29/07, Ramazan Ulker <ulkerra@gmail.com> wrote:
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.
Best Regards
Ramazan
