NFS problems 'Permission denied'

I have a DS415play and I have been trying to get the NFS working on it in conjunction with my laptop running Linux Mint 17.1 Mate.

I have tried it before with older versions of LM but no luck. Neither NFSv3 and NFSv4 seem to work.

I can mount the drives and access volume1, but anything beyond that I get a permission denied. Unless I access those directories as root (root on my laptop and not the administrator of the DS). I have tried syncing uid and gid and still no luck. I don't want to use squash.

I can access the DS with afp and smb but they are incredibly slow. I have tried turning of NSFv4 and still no luck. Idmapd is running.

I have a boxeebox running xbmc 13.1 that uses NFS as access and that has no problems at all.

It really is becoming very frustrating.

Anybody have any ideas?

EDIT: I figured it out.

It was a problem with permissions. Even though you can set permission to each of the local users themselves the local group (users) needs to have permission as well.

And now it works flawlessly.
