I'm having the same issue using autofs 5.0.4-3.1ubuntu5.1 on lucid.
When using NFS3 specifying replicated servers does work, when using NFS4 it
doesn't. If I run automount manually with verbose and debugging enabled I see
the
following output when trying to access /usr/local:

'get_nfs_info' seems to fail.
I can also confirm it does work properly on CentOS 5.5 running autofs
5.0.1.
