NFS driver appears to have inconsistent behavior when nas_secure_file_operations is set to auto

When deploying the NFS driver to our cloud I saw inconsistent behavior in the way the NFS share was accessed when nas_secure_file_operations was set to 'auto'. Currently we need to use root in our environment. It seemed that after first deployment it would not use the root user and then, after a restart, would sometimes switch to using the root user.

I wanted to get this documented. I plan to recreate and look into the problem more closely. Obviously, I was able to work around the problem by setting nas_secure_file_operations to 'False'.
