[Bug 1036647] [NEW] mount.cifs fails on mount DFS linked share

[Jonathan Davies]

Public bug reported:

mount.cifs fails to mount a DFS linked share on 12.04, this behaviour
worked fine on 10.04.

The DFS structure is:

\\SERVER1\TEST\SHARE-LINK which goes to \\SERVER2\LINKED-SHARE .

Mounting running:

$ sudo mount -t cifs //server1/TEST/SHARE-LINK /mnt/dfs-mount -o
user=Administrator

..fails on a precise machine, while it works on lucid.

My tests show that:

10.04 | mount.cifs works on oneiric and precise kernels.
12.04 | Stock kernel fails with both precise's mount.cifs and with lucid's mount.cifs compiled.

** Affects: linux (Ubuntu)
     Importance: Undecided
         Status: Incomplete

** Package changed: samba (Ubuntu) => linux (Ubuntu)
