RE: timeout on ldap_simple_bind_s()

More debug code is added to the wrapper: 
=======================================
static int ldap_simple_bind_ext_s( LDAP *ld, const char *dn, const char *passwd, struct timeval *timeout ) 
{
	int		msgid;
	LDAPMessage	*result;

            LOGINFO("debug ldap_simple_bind_ext_s timeout = %d ", timeout->tv_sec );

	if ( ld == NULL ) {
		return( LDAP_PARAM_ERROR );
	}

            LOGINFO("debug ldap_simple_bind_ext_s --1" );

	if ( (msgid = ldap_simple_bind( ld, dn, passwd )) == -1 )
		return( ldap_get_lderrno( ld, NULL, NULL ) );

            LOGINFO("debug ldap_simple_bind_ext_s --2 ");

	if ( ldap_result( ld, msgid, 1, timeout, &result ) == -1 )
		return( ldap_get_lderrno( ld, NULL, NULL ) );

            LOGINFO("debug ldap_simple_bind_ext_s --3" );

	return( ldap_result2error( ld, result, 1 ) ); 
}
=======================================
Just want to get a better understanding of the process. 

The log is quite confusing: 
=======================================

=======================================
It seems ldap_result() was not called. Isn't ldap_simple_bind() async func? Why does it behave like the sync one ldap_simple_bind_s()?
