Orthogonal is a single word, is precise and describes what is required
exactly. It has been in my vocabulary for approaching 30 years. None
overlapping range is three words and more characters as well. I was not
aware that Newspeak was now a requirement for posting on this list.

The SID's are set in stone, they have no UID's set in stone. Winbind to
work allocates a UID to them in it's allocatable (usually local)
database. There must be no conflicts between these allocated UID's and
the UID's in the domain, hence the requirement that the ranges given to
winbind be orthogonal.

Well that's relatively new (aka less than a year old). I guess not that
many enterprise distributions will carry it (though RHEL 6.4 does).

What gets me is people claiming that half a dozen lines of configuration
in smb.conf is more complicated than 30+ lines of configuration in an
entirely separate configuration file in addition to several lines in
smb.conf. It might be more performant, it might have fewer bugs etc. but
it is absolutely not simpler to configure.
