The bisect reported 302cabb739eb88e4c6c6ea50fce2a1f9201e2147 as the first bad commit. I built a Xenial test kernel with this commit reverted. The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1612135 Can you test that kernel and report back if it has the bug or not? Note, you will need to install both the linux-image and linux-image- extra .deb packages for this kernel.

What happens: permission denied even though there is permission I am denied access to the subfilesystems on a samba server. The top level filesystem itself is unaffected but dfs links seem to run into 'Operation not permitted' problems. When accessing the subfilesystem on the mount as root it mounts correctly. The standard user is then also able to access the subfilesystem. This only happens when the client uses kernel 4.4.0-34 (#53). When I revert my client to an older kernel (4.4.0-21) everything works. Using the older kernel the normal user can directly ls into the subfilesystem. This is bug is very similar to bug #1603719 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1603719). However, the released fix (in 4.4.0-33.52) does not seem to fix it for cifs.
