All,

I've a NFS4-mount on a CentOS Client with the following parameters:

(rw,soft,intr,tcp,port=2049,sloppy,addr=xxxx,clientaddr=yyyy)

This mount contains a rsync /home-Backup. All home-folders are owned by
nobody:nobody, stat displays uid and gid = 99. Folder permissions are
700.

I'm very surprised, that I can access my own home, but no foreign
folders, although it looks like permissions are all the same. There are
no facls set.

I cannot login on the NFS-server, but is it possible that NFS-client
shows wrong permissions?
