The netinfo(3) form of database is supplied with
the NeXT, NeXTSTeP, OpenStep, Darwin, Mac OS 10.0, and Mac OS X
operating systems. It is a network information service that provides
file contents such as aliases and
passwd, and locations such as the location of
the sendmail.cf file. If you are running on a
NeXT or under NeXTSTeP, this NETINFO will automatically be defined in
your operating system's
devtools/OS file. If you also define
AUTO_NETINFO_ALIASES, NETINFO will automatically be used to resolve
aliases. Otherwise, you will need to enable that use by declaring
netinfo: in an alias declaration or by including
netinfo in your service switch file (Section 12.1.1).
The netinfo(3) databases can also be used to
declare netinfo type maps (Section 23.2.2) with the K configuration
command.
If you are running a precompiled sendmail
binary, you can use the -d0.1 debugging
command-line switch (-d0.1) to determine if
NETINFO support is included (if it appears in the list, support is
included).
