ACL's with NFSv4

Hi all!

The situation is as follows: I have a machine with an ext3 partition
with POSIX ACL's. Now I would like to export this partition to another
machine as such that the homedirs on the source machine are available on
the target machine including ACL's. When I try to do this through NFS
then the ACL's are not available on target machine, and this causes the
owner/group perms to be incorrect.

NFSv4 apparently does support ACL's (altough they are similar to win NT
ACL's, but according to the docs POSIX ACL's should be mappable to NFSv4
ACL's), but I don't seem to be able to get this to work.

Both source and target machines use the same LDAP user backend, so I
would think there is no real need for id-mapping. On the source (server)
machine the /etc/exports looks as below:

/home 192.168.0.1(rw,sync,no_root_squash,fsid=0,insecure ,no_subtree_check)

and this is in the /etc/fstab file on the target (client):

192.168.0.10:/ /home nfs4
rw,hard,intr,proto=tcp,port=2049,noauto 0 0

The problem is that when I mount the homedirs on the target machine, all
directories have owner/group ownership by nfsnobody (uid=65534). Idmapd
runs on both machines and the config is as below:

$ cat /etc/idmapd.conf
[General]

Verbosity = 0
Pipefs-Directory = /var/lib/nfs/rpc_pipefs
Domain = localdomain

[Mapping]

Nobody-User = nobody
Nobody-Group = nobody

[Translation]
Method = nsswitch

What am I doing wrong?

Thanks!
