+ <title>DESCRIPTION</title>
+ <para>
+ The <filename>/etc/login.defs</filename> file defines the
+ site-specific configuration for the shadow password suite. This file
+ is required. Absence of this file will not prevent system operation,
+ but will probably result in undesirable operation.
+ </para>
+
+ <para>
+ This file is a readable text file, each line of the file describing
+ one configuration parameter. The lines consist of a configuration name
+ and value, separated by whitespace. Blank lines and comment lines are
+ ignored. Comments are introduced with a "#" pound sign and the pound
+ sign must be the first non-white character of the line.
+ </para>
+
+ <para>
+ Parameter values may be of four types: strings, booleans, numbers, and
+ long numbers. A string is comprised of any printable characters. A
+ boolean should be either the value <replaceable>yes</replaceable> or
+ <replaceable>no</replaceable>. An undefined boolean
+ parameter or one with a value other than these will be given a
+ <replaceable>no</replaceable>
+ value. Numbers (both regular and long) may be either decimal values,
+ octal values (precede the value with <replaceable>0</replaceable>) or
+ hexadecimal values
+ (precede the value with <replaceable>0x</replaceable>).
+ The maximum value of the regular and
+ long numeric parameters is machine-dependent.
+ </para>
+
+ <para>The following configuration items are provided:</para>
