Weird. With map file, it does work fine here (Network -> Servers ->
server name -> share)

In my /etc/exports:
# MacOS X (need map)
/nfs/server \
10.10.42.83(rw,sync,no_root_squash,map_static=/etc/nfs/osx.map,insecure)

and /etc/nfs/osx.map:
uid     0       0
uid     1-99    -
uid     65534   10000
gid     0       0
gid     1-49    -
gid     80      100
gid     70      1003
gid     65534   10000

ie: I map the user's OSX gid (70) to their Linux gid (1003) and I don't
worry about the UID, as these are shared folders only.

Note that you can't use nfs-kernel-server when using map_static, but
need nfs-user-server.

Admittedly a ugidd on OSX would be VERY useful :-)
