NAME
     nfsmapid - NFS user and group id mapping daemon

SYNOPSIS
     /usr/lib/nfs/nfsmapid


DESCRIPTION
     The nfsmapid daemon maps to and from NFS version 4 owner and
     ownergroup  identification attributes and local UID and GID
     numbers used by both the NFS version 4 client and server.


     nfsmapid  uses  the  passwd  and  group   entries   in   the
     /etc/nsswitch.conf  file  to direct how it performs the map-
     pings.


     The nfsmapid daemon  has  no  external,  customer-accessible
     interfaces.  You  can,  however,  administratively configure
     nfsmapid in one of the following ways:

         o    Specify the NFSMAPIDOMAIN parameter in nfs(4)

         o    Specify the nfsv4idmapdomain DNS resource record.


     Please refer to the  for further details.

ATRIBUTES
     See attributes(5) for descriptions of the  following  attri-
     butes:

       svc:/network/nfs/mapid




     Administrative actions on this service,  such  as  enabling,
     disabling,  or  requesting  restart,  can be performed using
     svcadm(1M). The service's status can be  queried  using  the
     svcs(1) command.


     If it is disabled, it  will  be  enabled  by  mountnfs(1M),
     sharenfs(1M),     and     automountd(1M),    unless     its
     application/autoenable property is set to false.


     nfsmapid caches a user's UID and GID. If a user subsequently
     changes  a  UID  or  GID,  using one of the utilities listed
     below, the nfsmapid cache becomes stale. At this point,  any
     NFS operation that gets or set attributes will result in the
     exchange of this stale information. To resolve  this  situa-
     tion, restart nfsmapid, as follows:

       # svcadm restart svc:/network/nfs/mapid:default




     The utilities that allow you to change UID and GID are:

         o    usermod(1M)

         o    userdel(1M)

         o    groupmod(1M)

         o    groupdel(1M)

         o    passmgmt(1M)


     The nfsmapid daemon might not exist in a future  release  of
     Solaris.
