 135     <title>DESCRIPTION</title>
 136     <para>
 137       The <filename>/etc/login.defs</filename> file defines the
 138       site-specific configuration for the shadow password suite. This file
 139       is required. Absence of this file will not prevent system operation,
 140       but will probably result in undesirable operation.
 141     </para>
 142
 143     <para>
 144       This file is a readable text file, each line of the file describing
 145       one configuration parameter. The lines consist of a configuration name
 146       and value, separated by whitespace. Blank lines and comment lines are
 147       ignored. Comments are introduced with a "#" pound sign and the pound
 148       sign must be the first non-white character of the line.
 149     </para>
 150
 151     <para>
 152       Parameter values may be of four types: strings, booleans, numbers, and
 153       long numbers. A string is comprised of any printable characters. A
 154       boolean should be either the value <replaceable>yes</replaceable> or
 155       <replaceable>no</replaceable>. An undefined boolean
 156       parameter or one with a value other than these will be given a
 157       <replaceable>no</replaceable>
 158       value. Numbers (both regular and long) may be either decimal values,
 159       octal values (precede the value with <replaceable>0</replaceable>) or
 160       hexadecimal values
 161       (precede the value with <replaceable>0x</replaceable>).
 162       The maximum value of the regular and
 163       long numeric parameters is machine-dependent.
