a problem about radius and ldap [SOLVED]

[Ramazan Ulker]

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)

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

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.
