[Bug 1097251] [NEW] NFSv4 server - no uid/gid mapping

[Stephane Mutz]

Public bug reported:

Configuration:
NFS server: Ubuntu 12.10
NFS client: CentOS 5.8

Using NFSv4 to export directories.

After having updated my Ubuntu server to 12.10, CentOS 5.8 NFS client
list all files directory as user / group nobody.

The setup was fully working in 12.04:
- idmapd.conf is fully configured on both client and server
- rpc.idmapd is running on both side
- uid/gid are identical on both side (using LDAP)
- LDAP authentication is working properly

Analyze logs on the client and network packets, the server is sending
uid/gid (numbers) when answering GETATTR request while the client is
expecting user at domain strings  (which is what another Ubuntu 12.04
server is sending), Increasing verbosity of rpc.idmapd on the server
didn't yield anything in the server logs. It seems that the uid to name
translation is not happening.
