Thanks for the hint!!
just mentioned that i set NEED_IDMAPD=y instead of =yes
Now the idmapd job can be started with service idmapd start.
However the logfile is empty:

local at vogone:~$ cat /etc/default/nfs-common 
# If you do not set values for the NEED_ options, they will be attempted
# autodetected; this should be sufficient for most people. Valid
alternatives
# for the NEED_ options are "yes" and "no".

# Do you want to start the statd daemon? It is not needed for NFSv4.
NEED_STATD=

# Options for rpc.statd.
#   Should rpc.statd listen on a specific port? This is especially useful
#   when you have a port-based firewall. To use a fixed port, set this
#   this variable to a statd argument like: "--port 4000 --outgoing-port
4001".
#   For more information, see rpc.statd(8) or
http://wiki.debian.org/SecuringNFS
STATDOPTS=

# Do you want to start the idmapd daemon? It is only needed for NFSv4.
NEED_IDMAPD=yes

# Do you want to start the gssd daemon? It is required for Kerberos
mounts.
NEED_GSSD=



local at vogone:~$ sudo vim /etc/default/nfs-common 
[sudo] password for local: 
local at vogone:~$ sudo service idmapd restart
restart: Unknown instance: 
local at vogone:~$ sudo service idmapd start
idmapd start/running, process 2295
local at vogone:~$ cat /var/log/idmapd.log

Title:
  rpc.idmapd refuses to start

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

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
