can't get quota over NFS4

[Denny Fuchs <linuxmail@4lin.net>]

hi,

I have several NFS4 mount with quota enabled on the server side (Wheezy too), but I only get quota for NFSv3.

"files" is our NFS server

=======================

mount:

files:/disc05 on /mnt type nfs4 (rw,relatime,vers=4,rsize=131072,wsize=131072,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=192.168.1.100,minorversion=0,local_lock=none,addr=192.168.1.1)

LANG="C" quota -u denny
Disk quotas for user denny (uid 14103): none


On the fileserver:

root@FILES:~# LANG="C" quota -u denny 
Disk quotas for user denny (uid 14103): 
     Filesystem  blocks   quota   limit   grace   files   quota   limit   grace

                  87796  490000  500000            6043       0       0        


what could be the reason?
