MSDfs and substitutions/default service..

[Kevin Wheatley]

Well I got my DFS working fine, but now I'm trying something more
complicated...

[global]
        default service = hidden_vdisk

[dfs]
        path = /dfsroot
        vfs object = /usr/samba/lib/VFS/vdisk.so
        msdfs root = yes
        writeable = no
        guest ok = no

[hidden_vdisk]
        path = /dfsroot/%S
        vfs object = /usr/samba/lib/VFS/vdisk.so
        msdfs root = yes
        writeable = no
        guest ok = no
        browseable = no

If I browse the '\\server\dfs' share I see directories under them, I
can then browse down and find a link that should be a DFS redirect and
it is, everything is OK.

If I now try browse '\\server\FOO' where 'FOO' is one of the
directories under /dfsroot, the macro expansion happens and I can
browse down fine, but the same DFS link is no longer a DFS link...
looking at the log it looks like sometimes the %S is remapped and
sometimes not so I get an error (see below)

Anybody suggest where to start?? If this works I'll have an almost
complete solution for emulating autofs style indirect maps.

Also is it possible for a share to be redirected ? e.g.

\\server1\share1 tells you to go to \\server2\share1
\\server1\share2 tells you to go to \\server3\othershare

from a quick look at what MS has to say about DFS I don't think so,
but then Samba can do other DFS things that they say they can't.

Thanks

Kevin


(NB I've replaced the real paths due to client request ...)
