apport information ** Tags added: apport-collected xenial
** Description changed: Similar like Bug #1603719 or Bug #1604396 i got a "Permission denied" when trying to access a NFS subshare from our NFSv4 Server. I tried this under (K)ubuntu Trusty and Xenial and also with the ubuntu based Mint Versions 17.3 Rosa an 18 Sarah. Kernel Versions higher than 4.4.0-31 from offical Ubuntu Repository has the problem. Before 4.4.0-31 not. For safety reasons i used the linux-generic-lts-wily meta package The 4.4 mainline kernel also works without problem currently (4.4.37-040437-generic) Our NFS server runs under FreeBSD 11, but same problems to the clients with FreeBSD 10.3 and OmniOS r151018. All NFS servers use ZFS as the filesystem and NFSv4 with kerberos for sharing. For the basic structure we use also ZFS filesystems. So my homefolder is located on the server under /apool/AIS/share/home/staff/fili/linux ... each level is a ZFS filesystem. On the client nfs share /apool/AIS/share/home is mounted under Similar Bug #1603719 or Bug #1604396 i got a "Permission denied" when trying to access a NFS subshare from our NFSv4 Server.

So my homefolder is located on the server under /apool/AIS/share/home/staff/fili/linux ... each level is a ZFS filesystem. On the client nfs share /apool/AIS/share/home is mounted under /home/VI My posix homedirectory path is /home/VI/staff/fili/linux When i try to login i got access to /home/VI/staff/fili ... but when i try to access the linux directory / zfs filesystem i got the permission denied. The fstab options for /home/VI are _netdev,rw,sync,sec=krb5,nfsvers=4,clientaddr=w.x.y.z I tried also autofs but with the same result.
