Hello there! Hope you can help. I´m running freeradius 2.1.6 on sles 11 and do LDAP-Authentificaiton on Radius. EAP/TTLS with cleartext-password against ldap works fine. PEAP/MSCHAP with universal password retrieval works fine. Ldap-Groups work fine. Load-Balancing with multiple ldap-servers also work fine. The only problem is: From time to time! the radius-debug fpr rlm_ldap says: rlm_ldap: ldap_get_conn: Checking Id: 0 rlm_ldap: ldap_get_conn: Got Id: 0 rlm_ldap: performing search in c=de, with filter (&(objectClass=inetOrgPerson)(uid=abc12345)) rlm_ldap: object not found So, radius doesn´t know the dn and can´t go on. The difference between other ldap searches and the one with this error is, that there is no new connect to the ldap-server and no new bind. Also, this never happens with the first access-request. Besides: A trace on my ldap servers shows no communication in that case (looks like radius doesntt ask after all) ... and: same problem appears with freeradius 2.1.1. Any ideas...??? Thank you very much... Kind regards Anja
