NAME
nss - configuration file for initgroups
SYNOPSIS
/etc/default/nssDESCRIPTION
The
/etc/default/nss configuration file provides methods for
initgroups(3C) lookup method. The file also provides a method to
disable address sorting by name lookup functions. The file controls
the behavior of the name service switch routines outside of the
source database mappings provided by the
/etc/nsswitch.conf file.
/etc/default/nss supports the following options:
NETID_AUTHORITATIVE Changes the behavior of the name service
lookups to use the
netid table in response to
the
initgroups() call. By default,
initgroups() uses the
group table. When
NETID_AUTHORITATIVE is set to TRUE,
initgroups() uses
netid as the source for
supplementary groups rather than the
group table.
The name service administrator must ensure
that the
netid table contains valid
supplementary group information for users. Not
all name services can automatically keep the
members listed in the
group table in sync with
the
netid table.
SORT_ADDRS If this option is set to FALSE, the sorting of
addresses is disabled on addresses that are
returned by name lookup functions such as
initgroups(),
gethostbyname(3NSL),
netdir_getbyname(3NSL),
getaddrinfo(3SOCKET),
and
getipnodebyname(3SOCKET). Setting this
option to FALSE is useful when the order of
addresses returned by the nameserver needs to
be maintained. To use the DNS round robin
feature, for example, address sorting by name
lookup functions should be disabled.
By default, address sorting is enabled.
