Hi, I am using Active directory as datasource for radius. I am getting "rlm_ldap: object not found or got ambiguous search result". I have configured ldap section as follows: ldap { server = "192.168.0.1" identity = "cn=sjadmin,ou=WID,dc=ecrt,dc=local" password = symbol basedn = "ou=WID,dc=ecrt,dc=local" filter = "(sAMAccountName=%{Stripped-User-Name:-%{User-Name}})" start_tls = no access_attr = "dialupacces" dictionary_mapping = ${raddbdir}/ldap.attrmap ldap_connections_number = 5 #password_header = "{SHA}" password_attribute = userPassword groupname_attribute = cn groupmembership_filter = "(|(&(objectClass=group)(member=%{control:Ldap-UserDn}))(&(objectClass=GroupOfUniqueNames)(uniquemember=%{control:Ldap-UserDn})))" groupmembership_attribute = radiusGroupName timeout = 4 timelimit = 3 net_timeout = 1 access_attr_used_for_allow = no } ldap_build_search_req ATTRS: dn ldap_send_initial_request ldap_send_server_request ldap_result ld 0x12026b140 msgid 7 ldap_chkResponseList ld 0x12026b140 msgid 7 all 1 ldap_chkResponseList returns ld 0x12026b140 NULL wait4msg ld 0x12026b140 msgid 7 (timeout 4000000 usec) wait4msg continue ld 0x12026b140 msgid 7 all 1 ** ld 0x12026b140 Connections: * host: 192.168.0.1 port: 389 (default) refcnt: 2 status: Connected last used: Tue Sep 23 21:21:01 2008 ** ld 0x12026b140 Outstanding Requests: * msgid 7, origid 7, status InProgress outstanding referrals 0, parent count 0 ** ld 0x12026b140 Response Queue: Empty ldap_chkResponseList ld 0x12026b140 msgid 7 all 1 ldap_chkResponseList returns ld 0x12026b140 NULL ldap_int_select read1msg: ld 0x12026b140 msgid 7 all 1 read1msg: ld 0x12026b140 msgid 7 message type search-result new result: res_errno: 0, res_error: <>, res_matched: <> read1msg: ld 0x12026b140 0 new referrals read1msg: mark request completed, ld 0x12026b140 msgid 7 request done: ld 0x12026b140 msgid 7 res_errno: 0, res_error: <>, res_matched: <> ldap_free_request (origid 7, msgid 7) ldap_free_connection 0 1 ldap_free_connection: refcnt 1 ldap_parse_result rlm_ldap: object not found or got ambiguous search result ldap_msgfree rlm_ldap: ldap_release_conn: Release Id: 0 Thanks, Pramada
