It may be tough to do with PAM as well because each time the user authenticates to a share the PAM module would increment the number of connections. How many connections should be allowed? 1 for IPC? 1 for the home directory? How about one for a printer? You could probably use a VFS module instead. You would need to write it. The way that I would do it is something along the lines of: grab examples/VFS/skel.c get rid of all the functions except skel_connect. Be sure to update vfs_init() and skel_ops appropriately. Replace all occurrences of skel_ with oneclient_ In oneclient_connect() (the function that used to be skel_connect()) add code that traverses the connections TDB looking for this user connected from a different machine. If the user is on from another machine, verify that connection is still good (kill(pid,0)) should work). If the tdb entry for the user on another machine and that smbd is really still alive, call default_vfs_ops.disconnect(). File a bug report on the problems that come up because you are calling disconnect() from connect(). I don't know that this will cause problems but I would expect that it could be asking for trouble. Then again, maybe that execution path has already been tested by something else. Mike

Users authenticate once to the server, then mount multiple shares on that connection.

There is currently no internal mechinism for dealing with this, but a PAM module might be able to construct a suitable solution. (Then setup samba --with-pam and 'obey pam restrictions' in smb.conf). But I dont use pam. Any other method?
