Ownership problem with NFS exported /home

[CB]

I have managed to get a user's home directory exported from an NFS
server, and can log that user in on the remote machine, using the
exported /home/<username>. 

However, all the files and directories in the home directory on the
client machine are shown to be owned by root/bin (uid 0 and gid 1). The
'real' files on the NFS server are definitely owned  by the user, and
the user & primary group id's are the same on server and client
machines.

The relevant entry in the server's /etc/exports is:

/home-ext/<username>           
192.168.0.1/24(rw,wdelay,insecure,root_squash,no_subtree_check,fsid=0,anonuid=65563,anongid=65535)

Anyone know what I am doing wrong, or can suggest how to troubleshoot
further?
