[jcifs] Problems accessing DFS share

[Johannes Martin]

Hi,

I've got a problem accessing a DFS share in our network using jcifs.

Here's a sample program to illustrate the problem:
---
import jcifs.smb.SmbFile;

public class TestSmbFile {
    public static void main(String args[]) throws Exception {
	SmbFile[] files = new SmbFile(args[0]).listFiles();
	for (SmbFile file : files) {
	    System.out.println(file.getPath());
	}
    }
}
---

In Windows, I can list the available shares by connecting to 
  \\my.domain.name\dfs

java TestSmbFile 'smb://<domain>;<user>:<pass>@my.domain.name/dfs/
gives me the following exception:
---
Exception in thread "main" jcifs.smb.SmbException: The network name cannot be 
found.

If I access the file server directly using
java TestSmbFile 'smb://<domain>;<user>:<pass>@server.my.domain.name/dfs/
I get the listing I expect.

java TestSmbFile 'smb://<domain>;<user>:<pass>@my.domain.name/
seems to list only the local shares of whatever server my.domain.name maps to 
(my.domain.name has multiple DNS entries, so I get one of three distinct 
servers), but not "dfs".

Is this a known limitation of jcifs or am I doing something wrong?
