NAME

     rpc.idmapd - NFSv4 ID <-> Name Mapper

SYNOPSIS

     rpc.idmapd [-v] [-f] [-d domain] [-p path] [-U username] [-G groupname]
                [-c path]

DESCRIPTION

     rpc.idmapd is the NFSv4 ID <-> name mapping daemon.  It provides
     functionality to the NFSv4 kernel client and server, to which it
     communicates via upcalls, by translating user and group IDs to names, and
     vice versa.

     The options are as follows:

     -v           Increases the verbosity level (can be specified multiple
                  times).

     -f           Runs rpc.idmapd in the foreground and prints all output to
                  the terminal.

     -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.

     -p path      Specifies the location of the RPC pipefs to be path.  The
                  default value is "/var/lib/nfs/rpc_pipefs".

     -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".

     -c path      Use configuration file path.

     -C           Client-only: perform no idmapping for any NFS server, even
                  if one is detected.

     -S           Server-only: perform no idmapping for any NFS client, even
                  if one is detected.

EXAMPLES

     rpc.idmapd -d "citi.umich.edu" -f -vvv

     Runs rpc.idmapd with the domain "citi.umich.edu" in the foreground,
     printing all messages to console, and with a verbosity level of 3.
