If you're not already running samba then you have to configure samba so
there would be the additional infrastructure.
If you've got more than one 'Linux' computer, how hard is it to ?
getent passwd | awk -F: '$3 > 499 && $3 < 10000 { print }' | grep -v '\
$' > /root/passwd.txt
getent shadow | awk -F: '$3 > 499 && $3 < 10000 { print }' | grep -v '\
$' > /root/shadow.txt
getent group | awk -F: '$3 > 499 && $3 < 10000 { print }' | grep -v '\
$' > /root/group.txt
copy these 3 files to the other 'Linux' machines and then simply cat
them onto the existing passwd/shadow/group files...
cat passwd.txt >> /etc/passwd
cat shadow.txt >> /etc/shadow
cat group.txt >> /etc/group
and then the UID mappings, GID mappings and passwords are all the same.
that would make user mounting of NFS quite simple
that would assure that user privileges are preserved as Unix/Linux
attributes where as with sambafs mounts, they are not.

yes it is free, they are also Microsoft protocols (smb and cifs) and
support for Unix attributes is not existent.
Curiously enough - Microsoft freely offers SFU - services for Unix -
free as in beer - I have situations where I make Windows Server speak
NFS instead of Linux systems speak smbfs. Different strokes for
different folks.

our perception of freedom is a philosophical debate
out perception of freedom from Microsoft products (fairly easy to do)
and File formats / patented & copyrighted technology (fairly difficult
to do) tends to stop at freedom from Microsoft shrink wrapped products
but that is only part of the equation.
