cups printing to Windows IPP Server

[António]

I have linux CUPS server with authentication for printers. When I use Windows XP with ipp its works but with linux box as a client and MacOSX it can't print nothing it gives me authentication errors. Do you know to  setup linux ipp client box or MacOSX ipp client box ?
