Hi,
I got a problem with a domain-based DFS share connection using JCifs 1.3.7.
In the application therere files send to a DFS-Namespace file system (with Active Directory). I actually use JCifs as a kind of URL Builder.
The code looks that way:
smbURL = new URL(url + filename);
URLConnection conn = smbURL.openConnection();
conn.setDoOutput(true);
targetStream = conn.getOutputStream();
Up to now I build the URL using a fully qualified servername to get the referral:
smb://<domain>;<user>:<pwd>@<servername (FQDN, e.g. server.company.com)>/<sharename>/<path>/<filename>
This works very well.
Now I want to replace this path with a domainbased DFS-link to make it more flexible.
smb://<domain>;<user>:<pwd>@<domain>/<dfslink>/<path>/<filename>
When I run the function with this DFS-link the method getOutputStream() returns a jcifs.smb.SmbException: The system cannot find the file specified.
The stack trace looks like that:
jcifs.smb.SmbException: The system cannot find the file specified.
jcifs.smb.SmbException: The system cannot find the file specified.

at jcifs.smb.SmbFile.getOutputStream(SmbFile.java:2793)
It seems at first attempt the server sends a PATH_NOT_COVERED errorcode and following by trying the referral a NO_SUCH_DEVICE (0xC000000E) error.
In Windows Explorer I reach the file system over that DFS-link without any problem.
The domain controller is Windows. The Fileserver is a NetApp-Filer.
After reviewing a lot of mailings I dont get any help on it.
I have no clue why the previous URL works but the new one doesnt. Wheres the difference in using domainbased link?
Kind regards,
Markus.
