[Samba] msdfs & full_audit issues

[Bill Baird]

I'm having issues enabling VFS full_audit & msdfs. It works great on
my non-root DFS servers. On my DFS root server, enabled full_audit
will break DFS links.

If found some reports of this from searching, but the users appear to
have resolved the issue from upgrading (to older versions that I am
using). I'm running Samba 3.6.9-167 on CentOS 6.

Here is an except from the samba server,

In Windows, the error for the client trying to click a dfs link is:

X:\'dfs share name' is not accessible
The specified network name is no longer available.

A copy of my share configuration is below.

Any help would be greatly appreciated!
