Which version of Ubuntu is this?  Your report doesn't mention.  (Please use
the 'ubuntu-bug' command for filing bugs, when possible.)

FWIW, this is no longer needed as of precise.

If you happen to be using precise, you can boot with --log to get logging of
upstart job output.  Otherwise, we can try to dissect this manually.  The
output of the start command suggests, however, that the pre-start script has
decided idmapd isn't meant to be started; so further debugging requires
knowing which Ubuntu release you're running.

Title:
  rpc.idmapd refuses to start

Status in “nfs-utils” package in Ubuntu:
  Invalid

Bug description:
  The following lines in /etc/fstab are missing:

  rpc_pipefs      /var/lib/nfs/rpc_pipefs rpc_pipefs      defaults        0       0
  nfsd    /proc/fs/nfsd   nfsd    defaults        0       0

  so rpc.idmapd refuses to start with this log:

  rpc.idmapd -v -f
  rpc.idmapd: libnfsidmap: using domain: blubberblase

  rpc.idmapd: libnfsidmap: loaded plugin
  /usr/lib/libnfsidmap/nsswitch.so for method nsswitch

  rpc.idmapd: Expiration time is 600 seconds.
  rpc.idmapd: nfsdopenone: Opening /proc/net/rpc/nfs4.nametoid/channel failed: errno 2 (No such file or directory)
  rpc.idmapd: main: open(/var/lib/nfs/rpc_pipefs/nfs): No such file or directory
