I remove  these code from linux to gcc.
a computer equipmented os win 2000 server  acts as server setting up AD .
i start a thread to init a ldap connection and bind them with a  valid account
and password,configured in server. then unbind them every several seconds.
 through special tools ,i can see that free memory always being decreasing.
 if i  only do action ldap_init,without bind to server,no the said scene .
THE CODE  IS :
 {  
    LDAP *ld;
    LDAPMessage *res=NULL, *e;
    int i;
    char *a, *dn;
    BerElement *ptr;
    char **vals;
    /* open a connection */
    if ( (ld = ldap_init("192.xxx.xxx.xxx",389 ))== NULL )
        return 1;
    if ( ldap_simple_bind_s( ld,"CN=nina
wang,CN=Users,DC=ldap,DC=qtier,DC=com","0000" ) != LDAP_SUCCESS )
    {
        ldap_perror( ld, "ldap_simple_bind_s" );
        return 1;
    }
      ldap_msgfree( res );
    /* close and free connection resources */
    ldap_unbind( ld );
    return 0;
}
Hope to receive your response soon. Thank you .
