Hi, I am testing the new NFS-server with Kerberos ,and interaction with Nfs-client, all based on Ubuntu-16.04 and sssd-13.4.

I have got a systematic "Permission denied" for owner accessing home directory , mounted on Nfs-client, with right permissions and right nfsidmapping.

In the syslog on the Nfs-server I found following messages - coming when resolving machine's principal name , and the file owner's principal name :

rpc.svcgssd[3126]: nfs4_gss_princ_to_ids: calling sss_nfs->princ_to_ids rpc.svcgssd[3126]: sss_nfs_princ_to_ids: not implemented

The strange thing is, that during login process I can mount homedir with right permissions and the right nfs name mapping !

kernel version for both , NFs-server/client is 4.4.0-31-generic #50 -Ubuntu;

The same Nfs-client mounts home directory from the old server (NFS+Kerberos, sssd-12.5) without problems.

Any idea?
