Upgrade your nfs-utils to the latest rawhide version (nfs-utils-1.0.6-31 
I believe)
to see if it take care of the problem. I think this has to do with the 
order of
how mountd and rpc.imapd are started. Basically mountd has to be running
before rpc.idmapd  for things to work...  So in  the case of the server 
(where
rpc.idmapd is already started), the nfs startup script send rpc.idmapd a 
signal
telling it to reopen its nfsd files (i.e. files under /proc/fs/nfsd )
