Yes; your patch solves this particular instance of the problem.  However, 
it still doesn't cover all potential case combinations, which mine does.  

It seems as though MS aren't particularly careful about the case they use
when obtaining tickets (see e.g. Q281401).  Adding extra principals to the
KDC and keytab for each server once you've discovered which ones you need
is trivial compared to patching Samba to add Yet Another Case Variation
and rolling out the patched smbd; I think it's therefore better for Samba
to cope with all potential case combinations out of the box.

What do you think?
