Johan -

Wow!  Now that's a very interesting piece of information.  And a
great demonstration (which I haven't been able to try yet) of the
facts of the matter.

Doesn't seem to be directly relevant to my clearcase problems
(I can't imagine rational actually taking advantage of something
as useful as this), but it's very informative.

Let me speculate:  I'll take at face value your example that you
can access the *same* share both ways.  Let's say userA has
read-only permissions for some files on the share, while userB
has read-write.

Let's say userC is logged onto the workstation.  After the net use
commands are executed, userC will be able to read, but not
write the 'file'
but will be able to both read and write the 'file'
even though these are actually the same file.

Very excellent!

Thanks for the insight.
