Mounting dfs with linux-cifs client

could someone with knowledge of DFS take a look at this thread:

The bottom line is, that the linux-cifs client cannot mount a service 
defined like this:

   msdfs root = yes
   msdfs proxy = \otherserver\someshare

Reason is, that samba returns BAD_NETWORK_NAME on attempts to connect 
this service. Changing the return value to PATH_NOT_COVERED resolved 
the problem. (See bottom)

Is this a bug? I could not check the behaviour of a windows server, 
because I couldn't figure out, how to configure the equivalent of 
"msdfs proxy", so that a service directly under the host is a DFS 

Thanks for any hints.
