nss - configuration file for initgroups
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.
