Can you check the uid and gid of the user on the client and the server ?
The user needs to have the same uid on both systems as NFS works with the
numerical IDs (uid/gid.)
This won't work:
Server:
bambi$ doas useradd -m -u 10000 -g 10000 test
bambi$ doas mkdir /exports/test3
bambi$ doas chown test:test /exports/test3
Client:
creith@molloy:~$ sudo useradd -m -u 10001 -g 10001 test
creith@molloy:~$ sudo su - test
test@molloy:~$ touch /mnt/test3/hallo
touch: '/mnt/test3/hallo' kann nicht ber??hrt werden: Keine Berechtigung
Sorry for the German, it means: Permission denied.
