-Setting up MS Dfs in Samba
-kalele@veritas.com March 2000
-
-Currently, MS Dfs support is a configure time parameter (--with-msdfs). Can be changed later to always compile it in..
-
-To have a server announce itself as a Dfs server, add a "host msdfs=yes" entry to smb.conf.
-
-To make a share a Dfs root, add a "msdfs root=yes" entry to the share definition
-in the smb.conf file.
-e.g.
-[pub]
- path = /export/publicsmb
- msdfs root = yes
-
-To create dfs volumes/junctions in the share, create symbolic links of the
-format msdfs:server1\share1,server2\share2 and so on.
-
-In the above example, create a dfs volume "dfsstorage" in the [pub] share as:
-cd /export/publicsmb
-ln -s msdfs:serverA\\share dfsstorage
-
-Clicking on dfsstorage from a dfs-aware client will show you the contents of
-\\serverA\share
-
-Shares with "msdfs root = no" (which is the default) entries are served as normal
-shares and the client stops talking Dfs with Samba after a tconX.
-
-NOTES:
-* Windows clients need to be rebooted if a non-dfs root is made a dfs root or
- vice versa. A better option is to introduce a new share and make it the dfs root.
-* Currently there's a restriction that msdfs symlink names should be all
- lowercase.
