I'm currently using samba4 active directory based kerberos with NFS4
(and windows shares) and prior to that i also used MIT kerberos
successfully without any issue.

On the NFS4 server:

cat /etc/exports

/srv/nfs4             *(rw,async,root_squash,crossmnt,fsid=0,sec=krb5i,no_subtree_check)
/srv/nfs4/Benutzer    *(rw,async,sec=krb5i,no_subtree_check)
.....


cat /etc/default/nfs-common
NEED_STATD=no
STATDOPTS=
NEED_IDMAPD=yes
NEED_GSSD=yes

Could you double check, that the kerberos keytabs for the services are
properly configured. You might also check that dns is working properly.

You need to specify "-o sec=krb5i" when mounting (at least I do that
here). I also use the fqdn of the server.
