Yes, I know.

But doesn't hurt anywhere AFAIK. It's just another proof that their
fork is not very well thought out and executed.

I have not (yet) looked into this (no appropriate Windows system 
around here right now)...

But be aware, that Microsoft's so-called IPP implementation is based
on IPP 1.0 (which never made it into an official standard, only into
a "draft"), not IPP 1.1 (which *is* an officially recommended IETF 
standard). Also, MS use their own Windows authentication scheme 
(which is not exactly famous for its interoperability) for their 
secure IPP 1.0 printing (to be fair, IPP 1.0 papers do not at all 
talk about authentication, that only has been added into IPP 1.1).

Cheers,
Kurt
