manual for rpc.idmapd offers arguments which do not exist

From the manual page:

     -d domain Set domain to domain. This is used internally by NFSv4 and
                  is typically assigned by the system administrator. By
                  default, domain is set to be the FQDN of the host, minus the
                  hostname.

     -U username Specifies the NFSv4 nobody user to be username. The default
                  value is "nobody".

     -G groupname
                  Specifies the NFSv4 nobody group to be groupname. The
                  default value is "nobody".

However:

# rpc.idmapd -d kinetic -f -vvv
rpc.idmapd: the -d, -U, and -G options have been removed; please use the configuration file instead.

The documentation should be edited to reflect reality.
