Would like to discuss the issue I am facing before opening bug report.
NFS System: latest Debian Jessie
NFS: nfs-kernel-server 1:1.2.8-9
Export config:
/data/folder @clients(rw,no_subtree_check,root_squash)
Netgroup config:
root@media:~# cat /etc/netgroup
clients (dm800,-,), (laptop,-,)
root@media:~# grep netgroup /etc/nsswitch.conf
netgroup: files
I don't have rw access to mounted folder. Once migrated to configuration without netgroup the permissions allow rw access as expected.
