I've never used DFS so I'm not sure what u mean by having to reply with a redirect of "\server\share\home/userluser/eLItE\haXor/".  Do u mean it has to have a way of interpreting that string or that it should send a redirect to the client saying "u really want this path...".  I think there's a few ways to resolve the ambiguity.  First is to explicitly set the path seperator.  Second would be to infer the path seperator from the first char after the share name. A backslash in the above example.  A third option would be to retain mixed seperators and require a double backslash escape of literal backslashes.  My preference would be to require all backslashes as the sole path seperator and escape literal backslashes like we escape them everywhere else.  A left field possibility would be to require paths to be passed to the server as struct's of some kind.  That would obviate the problem.

The problem for me is in POSIX pathname processing
(when both server and client support the UNIX extensions).

Currently the client would send a pathname of :

"/home/userluser/eLItE\haXor/" and the smbd server
would interpret it as :

"/home/userluser/eLItE/haXor/"

which is incorrect. Now that's easy to fix, but
the problem is when the client is in unix extensions
posix pathname mode and accesses a DFS share which
needs to reply with a redirect of :

"\server\share\home/userluser/eLItE\haXor/"

Jeremy.
