The problem exists already in the Linux kernel. smbfs (and probably ncpfs too)
have it. smbfs currently uses the 'specify user at mount time' hack, but that's
only a bad hack IMHO and not suitable for multiusre machines. I'm sure
the smbfs developers are interested in solving this problem too (I cc'd
Bill Hawes)
