Solaris Naming Setup and Configuration Guide

Preparing the `Makefile`

After checking the source files and copying them into the source file directory, you now need to convert those source files into the ndbm format maps that the NIS service uses. This is done automatically for you by ypinit when called on the master server, as explained in the next section, "Setting Up the Master Server With ypinit".

The ypinit script calls the program make, which uses the Makefile located in the /var/yp directory. A default Makefile similar to Example 10-1 is provided for you in the /var/yp directory and contains the commands needed to transform the source files into the desired ndbm format maps.

You can use the default Makefile as it is, or modify it if you want. (If you do modify the default Makefile, be sure to first copy and store the original default Makefile in case you need it for future use.) You may need to make one or more of the following modifications to the Makefile:

Nondefault maps. If you have created your own non-default source files and want to convert them to NIS maps, you must add those source files to the Makefile.
DIR value. If you want the Makefile to use source files stored in some directory other than /etc as explained in "Source Files Directory", you must change the value of DIR in the Makefile to the directory that you want to use. When changing this value in the Makefile, do not indent the line.
PWDIR value. If you want the Makefile to use passwd, shadow and/or adjunct source files stored in some directory other than /etc, you must change the value of PWDIR in the Makefile to the directory that you want to use. When changing this value in the Makefile, do not indent the line.
Domain name resolver. If you want the NIS server to use the domain name resolver for machines not in the current domain, comment out the Makefile line B=, and uncomment (activate) the line B= -b.

Example 10-1 Default Makefile Before Modification

# "@(#)Makefile 1.15 95/05/05 SMI"
#
# It is somewhat confusing to note that Solaris 2.x uses
# /etc/auto_master instead of the 4.x /etc/auto.master file name
# because of NIS+ treating a "." in a special way.
#
# Set the following variable to "-b" to have NIS servers use the
# domain name resolver for hosts not in the current domain.
#B=-b
B=
DIR =/etc
#
# If the passwd, shadow and/or adjunct files used by rpc.yppasswdd
# live in directory other than /etc then you'll need to change the
# following line.
# DO NOT indent the line, however, since /etc/init.d/yp attempts
# to find it with grep "^PWDIR" ...
#
PWDIR =/etc

The function of the Makefile is to create the appropriate NIS maps for each of the databases listed under all. After passing through makedbm the data is collected in two files, mapname.dir and mapname.pag, both in the /var/yp/domainname directory on the master server.

The Makefile builds passwd maps from the /PWDIR/passwd, /PWDIR/shadow, and /PWDIR/security/passwd.adjunct files, as appropriate.
