dear Pierangelo Masarati:
 thank you for your response.
now  i have call ldap_simple_bind() function  but it will return for a long time(almost  60    seconds, and i am working in linux redhat as 4, openldap2.2),
 but  the man doc says this is a asyschronized function, any option should
 i set the pLdapConnection ?
 
 
 if ((msgid = ldap_simple_bind(pLdapConnection, pUserDN, pPassword)) == -1)
/*ldap_simple_bind() return for 60 seconds if the server wrong or down.*/
...
...
 ret = ldap_result(pLdapConnection, msgid, LDAP_MSG_ALL, &     tv_select_timeout, &result);

cheers, 

lijx
