nfsmapid(1M) System Administration Commands nfsmapid(1M)NAMEnfsmapid - 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
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 Specify the NFSMAPID_DOMAIN parameter in nfs(4)
o Specify the _nfsv4idmapdomain DNS resource record.
Please refer to the for further details.
FILES
/var/run/nfs4_domain Contains the domain name currently used by
NFSv4.

NOTES
The nfsmapid service is managed by the service management facility,
smf(5), 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(1M). The service's
status can be queried using the svcs(1) command.
If it is disabled, it will be enabled by mount_nfs(1M), share_nfs(1M),
and automountd(1M), 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(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.
