To tell the SunOS 4.1.X system to use the NIS database for passwd and group files put entries such as:
as the last entry in the /etc/passwd file of the NIS clients, i.e. all NIS password entries are valid on this host. Other examples of limitations and exclusions are, for /etc/passwd:
+frank: - frank is a valid user, use his entry from the NIS database.
+frank:::::/home/new/frank: - frank is a valid user, all entries are as in the NIS database, except his
+@group:*:0:0:::/bin/true - the group "group" can't login, but users in this group can refer to their home directories.
-@group::0:0::: - exclude this group from entry.
and for /etc/group:
+: - all entries in the NIS group database are valid here.
+group: - the NIS group "group" is valid.
+project:::frank,bob - only the member frank and bob of group "project" are valid.
SunOS 5.X clients will use the NIS database if nis and compat (for NIS +/- entry compatibility) are specified for the passwd entry in /etc/nsswitch.conf, e.g.:
passwd: compat files nis
To use the default NIS passwd table there is no need to add additional entries to /etc/passwd on the SunOS 5.X client.
