Bug Description: Net::LDAP password modify extop breaks; msgid in response is 0xFF
Reviewed by: ???
Branch: HEAD
Fix Description: We use a fake conn for the internal password modify operation
so that we can use the real credentials.  Unfortunately, this messes up the
result code - because there is a real, non-NULL conn, it thinks it needs to
send the result back to a real client rather than handle it as an internal
operation.  It looks as though o_result_handler is only used for internal
operations.  The fix is to change the result handling code to check for
an internal op OR conn == NULL to see if we should use the result handler
instead.
