Hello All I am experiencing a problem while trying to authenticate the username/password in LDAP through a freeradius server. While a regular telnet/ssh to the edge running a openLdap client / PAM module works fine (It is able to authenticate) but the problem arises when trying to authenticate using the freeradius server . This is what the log message looks like : User-Name = "try" User-Password = "trialanderror" NAS-IP-Address = 127.0.0.1 NAS-Port = 2 Processing the authorize section of radiusd.conf modcall: entering group authorize for request 0 modcall[authorize]: module "preprocess" returns ok for request 0 modcall[authorize]: module "chap" returns noop for request 0 modcall[authorize]: module "mschap" returns noop for request 0 rlm_realm: No '@' in User-Name = "try", looking up realm NULL rlm_realm: No such realm "NULL" modcall[authorize]: module "suffix" returns noop for request 0 rlm_eap: No EAP-Message, not doing EAP modcall[authorize]: module "eap" returns noop for request 0 users: Matched entry DEFAULT at line 152 users: Matched entry DEFAULT at line 155 modcall[authorize]: module "files" returns ok for request 0 rlm_ldap: - authorize rlm_ldap: performing user authorization for try radius_xlat: '(uid=try)' radius_xlat: 'ou=People,dc=example,dc=com' rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: attempting LDAP reconnection rlm_ldap: (re)connect to 30.0.0.2:389, authentication 0 rlm_ldap: bind as / to 30.0.0.2:389 rlm_ldap: waiting for bind result ... rlm_ldap: Bind was successful rlm_ldap: performing search in ou=People,dc=example,dc=com, with filter (uid=try) rlm_ldap: Added password {crypt}$1$2Pl0Lm5O$ot8mrXYBaAg12RoBogNDK. in check items rlm_ldap: looking for check items in directory... rlm_ldap: looking for reply items in directory... rlm_ldap: user try authorized to use remote access rlm_ldap: ldap_release_conn: Release Id: 0 modcall[authorize]: module "ldap" returns ok for request 0 modcall: group authorize returns ok for request 0 rad_check_password: Found Auth-Type LDAP auth: type "LDAP" Processing the authenticate section of radiusd.conf modcall: entering group Auth-Type for request 0 rlm_ldap: - authenticate rlm_ldap: login attempt by "try" with password "trialanderror" rlm_ldap: user DN: uid=try,ou=People,dc=example,dc=com rlm_ldap: (re)connect to 30.0.0.2:389, authentication 1 rlm_ldap: bind as uid=try,ou=People,dc=example,dc=com/trialanderror to 30.0.0.2:389 rlm_ldap: waiting for bind result ... rlm_ldap: Bind failed with invalid credentials modcall[authenticate]: module "ldap" returns reject for request 0 modcall: group Auth-Type returns reject for request 0 auth: Failed to validate the user. Delaying request 0 for 1 seconds Finished request 0 Going to the next request --- Walking the entire request list --- Waking up in 1 seconds... --- Walking the entire request list --- Waking up in 1 seconds... Here you can see that the authorization of a user 'try' having password 'trialanderror' works fine but authentication fails. The host running the freeradius server is Fedora Core 5 running linux 2.6.25. Could you please suggest where we are going wrong. I am sending you a copy of the /etc/raddb/users file as well. DEFAULT Auth-Type = System Fall-Through = 1 DEFAULT Auth-Type := LDAP Fall-Through = 0 Any help would be gratefully appreciated. Thanks Sambuddho
