NFS4 mount shows all ownership as 4294967294

[jemartins]

Hi,

I get one server exporting /home via nfs with Mandriva 2011 and authenticating via LDAP . See /etc/exports:

/home lab*(root_squash,sync,secure,subtree_check,rw)

The server are running nfs-server and rpc.idmapd.

In the client side, I have Mageia 3 and I can mount /home. See /etc/fstab:

server:/home /home nfs4 exec,dev,suid,rw,bg 0 0

The client are running rpc.idmap also

But If I run ls -la in one directory on the nfs partition, I get 4294967294 as ownership (the group is OK):

drwxr-xr-x 22 4294967294 alunos 4096 Mai 30 12:03 yuftas/

Anybody knows the solution. I had searched in google but there is nothing specific for Mageia 3.

A quick google search for "nfs share wrong uid" reveals dozens of hits:

NFS is nothing specific to Mageia 3, it's common for all *nices

If I try this workaround:

echo 400000 > /proc/sys/kernel/keys/root_maxbytes
echo 10000 > /proc/sys/kernel/keys/root_maxkeys

The problem is temporally fixed.

I think it is a bug and did a bug report:
