Network Information Service Plus (NIS+)
NIS+, the next generation of the Network Information Service (NIS), was
introduced in HP-UX Release 10.30 and is supported in both standard
and trusted HP-UX systems. NIS+ is not an enhancement to NIS; it is a
whole new service. Like NIS, it is a distributed database system that
allows you to maintain commonly used configuration information on a
master server and propagate the information to all the hosts in your
network. NIS+ is described in detail in Installing and Administering
NFS Services.
NOTE NIS is still supported on standard systems. You do not have to change
your NIS configuration. NIS is not supported on Trusted Systems.
HP-UX can support an NIS+ configuration that includes HP-UX
standard and Trusted Systems and non-HP-UX systems. Users access
their login systems in the usual way.
As an HP-UX extension to NIS+ for Trusted Systems, an HP-UX NIS+
server runs the ttsyncd daemon to synchronize the NIS+ password table
with the NIS+ trusted table. HP-UX Trusted System clients can access
that database. If the NIS+ server is not an HP-UX system, HP-UX
Trusted System clients must maintain local Trusted System databases.
NOTE In a Trusted System, the NIS+ user password length is limited to 8
characters for interoperability reasons, whereas more than 8 characters
are allowed for local users.
