NFSMAPID(8) Maintenance Commands and Procedures NFSMAPID(8)
NAME
nfsmapid - NFS user and group id mapping daemon
SYNOPSIS
/usr/lib/nfs/nfsmapidDESCRIPTION
The
nfsmapid daemon maps to and from NFS version 4
owner and
owner_group 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 mappings.
The
nfsmapid daemon has no external, customer-accessible interfaces.
You can, however, administratively configure
nfsmapid in one of the
following ways:
+o Set the
nfsmapid_domain property for the
nfs protocol using
sharectl(8).
+o Specify the
_nfsv4idmapdomain DNS resource record.

The
nfsmapid service is managed by the service management facility,
smf(7), under the service identifier:
svc:/network/nfs/mapid
Administrative actions on this service, such as enabling, disabling, or
requesting restart, can be performed using
svcadm(8). The service's
status can be queried using the
svcs(1) command.
If it is disabled, it will be enabled by
mount_nfs(8),
share_nfs(8),
and
automountd(8), unless its
application/
auto_enable 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 situation, restart
nfsmapid, as follows:
# svcadm restart svc:/network/nfs/mapid:default
The utilities that allow you to change UID and GID are:
+o usermod(8) +o userdel(8) +o groupmod(8) +o groupdel(8) +o passmgmt(8)illumos March 12, 2016 illumos
