Is it just Win9X ? because I notice there is some code to detect the
client OS in some parts of samba, in this case you could only
strlower() on those client you know have the upper case 'feature' (or
perhaps the reverse and don't do it on those you know work with mixed

Thinking about this more, (and grepping the code for 'DFSPATH') I
notice that unix_convert() is called all over the place, is there a
reason why this couldn't be called once per request in a more central
place so that at any time you've got access to the requested file and
the file it should map to ? Perhaps some kind of run once macro may be
suitable to cache the result allowing the sprinkling of the calls
throughout the code thus getting a form of lazy evaluation + caching

Not that I'm offering to do this, as I don't know the code well enough
to trust me to do it :-)

or am I simply playing a different ball game all together ?
