insert "ldap_unbind( ld );" here. Does that fix the problem? That's how to free the LDAP* structure.

In LDAP, "unbind" is the "disconnect" command, it's not the opposite of "bind". The misleading name came about because originally one had to bind after connect.

    return 1;
}
  ldap_msgfree( res );

res == NULL here in this particular code, so you can drop this and the declaration of 'res'.

/* close and free connection resources */
ldap_unbind( ld );
return 0;

}
