hello shirish, we made some more experiments with the dfs-code and now have a running solution for our smb-proxy, without breaking msdfs (well, i didn't had a look on the dfs_rpc-pipe for now...)
you can now have a samba-share behave like an mdfs-symlink.
if you set a share to "msdfs proxy = yes" and declare the link in its
path to "msdfs link name = linkname" the clients will reveive correct
referrals already when they access the share :)
since we are planning to use this patch in production, it would be very
nice if you could comment on this.
-----8<------------------snip--------------8<--------------
add to smb.conf:
[global]
host msdfs = yes
[dfs-fake]
path = /export/dfs-fake
msdfs root = yes
msdfs proxy = yes
msdfs link name = "linkname"
create a link:
ln -s msdfs:unimak\\storage /export/dfs-fake/linkname
----->8------------------snap-------------->8--------------
thanks a lot,
guenther
