Ubuntu Desktop 16.04.3 LTS Kernel - 4.10.0-40-generic cifs-utils - 2:6.4-1ubuntu1.1 samba & smbclient - 2:4.3.11+dfsg-0ubuntu0.16.04.12
We are a large company with a Windows Server backend and a mix of Windows, MacOS, CentOS and Ubuntu clients. We use DFS heavily for file share management.
Recently, we've begin disabling SMB v1 on the servers to mitigate its associated vulnerabilites. This has not been any trouble for the Windows or Mac clients, however, the Ubultu and CentOS clients are having a lot of trouble.
Specifically, mounting a DFS share fails once the client tries to see past the symbolic link that points to the absolute path.
//namespaceserver/share/directory/symboliclink points to
This is the command I'm using:
sudo mount.cifs //namespaceserver/share /mnt/share -o vers=2.1,email@example.com'
The mount is successful and I can navigate within the DFS namespace but, once I try to go past the symbolic link, I get:
ls: cannot access '/mnt/share/directory/symboliclink': Function not supported.
follow symlinks=yes and
unix extensions=no to the smb.conf file but that didn't help.
Any advice would be appreciated as I've spent about ten hours on this issue so far.
