You have kind of answered your own question here. If you need root
access to the files from the client, you will need the 'no_root_squash'.
All that option does is honour your clients root user over the NFS share
(not great for security but I don't know your set up details).

Other than that you'd have to manage the users on both systems, to be
the same name/uid/gid etc.. and do everything as a non-root user (better
for security).

Take a look at this link[0] and hopefully that should clear it all up.


Thanks,
Michael

Michael,
In following situation if I access as root or non-root, I am facing same "Permission denied" error.
So the problem is just not with root but all users.

client# ls -l /borneo4
ls: cannot access /borneo4/test-dir: Permission denied
?????????? ? ? ? ?                ? test-dir
client# su - eos
client$ ls -lh /borneo4/
ls: cannot access /borneo4/test-dir: Permission denied
total 0
?????????? ? ? ? ?                ? test-dir



And on server side I am ready change file permissions. By changing ownership of directory will solve this problem without using no_root_squash ?
