Public bug reported:

Binary package hint: nfs-common

I have an edgy and a feisty box. It is possible to mount stuff with nfs3
from/to each other. When I try nfs4 it also mounts correctly but the
remapping of userids does not fully work. This problem exists when I
export on feisty and mount on edgy as well as the other way round.

The userid being 501 and 1000 on the other system respectively, idmapd
seems to correctly translate between the two hosts. I can check with
ls(1) and see the correct (translated) username. But when I try to write
data I get permission denied.

I am pretty sure this is a uid mapping problem because I can write data
on the nfs4 share as root when I export with no_root_squash.

idmapd.conf on both systems is identical, with Domain set to "local".

exports looks like this on both systems:

  /export         192.168.1.0/24(rw,fsid=0,sync,no_subtree_check) 
127.0.0.1/8(rw,fsid=0,sync,no_subtree_check)
  /export/data   192.168.1.0/24(rw,nohide,sync,no_subtree_check) 
127.0.0.1/8(rw,nohide,sync,no_subtree_check)

Mount has been done with the following command:

  mount -t nfs4 otherhost:/ /import/otherhost

Can somebody confirm this?
