Thanks Pshem for your quick answer. 

I expect answer like folowing 

"rlm_ldap: user jjeep authorized succesfully 
   modcall[authorize]: module "ldap" returns ok" 

But I got 

"rlm_ldap: object not found or got ambiguous search result 
rlm_ldap: search failed 
rlm_ldap: ldap_release_conn: Release Id: 0 
  modcall[authorize]: module "ldap" returns notfound for request 0" 

Thanks 
Robin
