Ok, I have a couple of suggestions, which should not necessarily be
implemented in this order. :)
1) Ditch webmin, I don't know what it is but it seems to break
something that should be pretty simple to set up, without giving any
feedback.
2) If the problem involves some files that do not exist, please list
them, maybe it's a clue that something important is missing.
3) NFS is well documented in the man-pages, but has a pathetic
documentation online. Try "man nfs" and "man exports".
4) As somone else mentioned, do not mess with idmapd, since you have
the UIDs synced already.
5) Until a few weeks ago my main NFS server was wheezy, but I am now
using stretch. My files looks like this:
On the (stretch) server: /etc/exports contains:
/srv/stuff 1.2.3.0/24(sec=sys,rw,no_subtree_check,mp,root_squash)
On the (jessie) clients: /etc/fstab contains:
name_of_server:/srv/stuff /stuff nfs4 _netdev,rw,auto,bg
You shouldn't have to change any other files, really, but I can't
remember if this has something that's not supported on wheezy.
