I guess this doesn't always work because 'A' may convert to 'a' in English,
but the same 'A' may convert to '&' or something in another language? But
the same unicode capital A would be used in both char sets, so
server-folding would be partial guesswork?

Can you explain your thinking? My perspective is that: the server is doing
comparisons between filenames (to check for uniquness). If it's being used
to version control an insensitive filesystem, it needs to reflect that
internally, or inconsistensies will result.

If it could be done in the client libs great, but how? If the server allows
dirs 'A' and 'a' to be created, you just can't check that out any more in a
insensitive OS..

If the client lib did the unique check, youd have to send the entire dir
contents to the client, and allow it to perform the check. That would be
too slow?

Plus that would allow a Linux client to create entries not accessable
from win32, which may not be desirable.

Thanks for the help,

John
