[jcifs] Issue for connecting to DFS root

[Kambiz Niktabar]

Hi,

Actually we are using Apache ManifoldCF windows share/dfs connector 
which it uses JCIF in the background to connect to the 

shared folders. It works fine with the shared folders on the servers but 
we have some issues with connecting to the DFS root 

since we got the following errors. Do you have any idea what the issue 
is and how it can be resolved?
