928 | Chapter 23: The K (Database-Map) Configuration Command
The nis database-map type is available only if sendmail is compiled withNIS defined
(?§3.4.35 on page 128).
23.7.15 nisplus
Sun??™s newer version of NIS V8.7 and later
Sun Microsystems??™ NIS+ is a complete redo of its earlier NIS system. The nisplus type
allows you to look up information using NIS+. The form of that type declaration looks like
this:
Kname nisplus nismap.domain
Here, the nismap is an NIS+ database-map name, suchas mail_aliases.* If the domain or
.domain is missing, the nisplus default domain is used. If the entire nismap.domain is missing,
the default becomes mail_aliases.org_dir. The domain org_dir contains all the systemwide
administration tables.
Any lookup failures that can be retried will automatically be retried up to five times, with a
sleep(3) of 2 seconds between eachtry. If the map.domain doesn??™t exist in the local NIS+
system, no error is reported.
Only a modest number of database switches are available for this type. They are listed in
Table 23-20.
-N ?§23.3.8 on page 889 Append a null byte to all keys.
-O ?§23.3.9 on page 889 Never add a null byte.
