[jcifs] canWrite() question

[Michael B Allen]

The canWrite and canRead methods are somewhat useless. They just check the
"Read only" bit of the file attributes. JCIFS does not inspect a file's
ACL and perform an access check using the identity of the current user. We
don't integrate properly with Java's Subject based security model.

The only way to tell if you can write a file is to actually try and open
it for writing with new SmbFileOutputStream.
