NIS (formerly called Yellow Pages) allows network management of
|
|
important administrative files (e.g. the password file). For more
|
|
information refer to the NIS manpage and <ulink url="&url.nis;">
|
|
Introduction to YP/NIS</ulink>. There is also a book called <ulink
|
|
url="&url.nis.book;">Managing NFS and NIS</ulink> by Hal Stern.

To get these functions to work, you have to configure PHP with
|
|
<option role="configure">--with-yp</option>(PHP 3) or
|
|
<option role="configure">--enable-yp</option>(PHP 4).

A NIS domain can be described a group of NIS maps. Every host

that needs to look up information binds itself to a certain
