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.
