help with mapping user home folders

I have NFS setup and can successfully mount my shared media folder.
I have set this up in fstab to be done at boot up for all users.

I can't seem to mount the users home folder though.
I would like the user home folder to be mounted at login for each user without visibility to the other user folders.

grateful for a helping hand.

i think i need more fundamental moment. I managed to get the home directories to map manually after running the exportfs command. however,

1) media directory - mapped via fstab
nasbox:/media /mnt/nasbox/media nfs rw,hard,intr 0 0
problem here is that all users have read/write so it doesn't pay attention to the permissions on the nasbox.
I want all users except myself to be read only. (this works the way i want on the windows machine via samba i.e. r/o for all except me)

2) home directories
sudo mount boxip:/Home /mnt/nasbox/home
all users directories appear and they are all r/w. Ideally, i only want the current logged in user to be mapped or map-able.

In the end, i used the following commands in fstab of the client

IPAddress:/media /mnt/nas/media nfs users,rw,auto 0 0
IPAddress:/Home /mnt/nas/home nfs users,rw,auto 0 0

This works with the users getting the correct rights i.e. standard user has ro for the media and rw for the home/user directory.
can see home/admin but cannot enter the directory.

I have no problems copying files from the client to the nas and retaining the correct rights.
i replaced the users-dirs.dirs paths with the nas paths on the client which sets unity up nicely.

However, i am having a problem when saving from an application directly. i.e. Libreoffice or Word-wine.
Files are being saved with nobody as the owner with no read, no write access. group is listed as -2 with none as access.
the uids match on the two systems, so i guess this maybe related to gids? but which groups to i need to match the ids on then?
