nekral-guest 7ce94164c7 * man/login.defs.d/SYS_UID_MAX.xml, man/login.defs.d/SYS_GID_MAX.xml: 
Document new variables.
* man/newusers.8.xml, man/login.defs.5.xml,
  man/login.defs.d/GID_MAX.xml, man/login.defs.d/UID_MAX.xml:
  newusers uses now the GID_MAX, GID_MIN, UID_MAX, UID_MIN,
  SYS_GID_MAX, SYS_GID_MIN, SYS_UID_MAX, and SYS_UID_MIN variables.
* man/groupadd.8.xml, man/login.defs.5.xml: groupadd uses now the
  SYS_GID_MAX, and SYS_GID_MIN variables.
* man/login.defs.5.xml: useradd uses now the SYS_GID_MAX,
  SYS_GID_MIN, SYS_UID_MAX, and SYS_UID_MIN variables.

<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>

Much of the functionality that used to be provided by the shadow
password suite is now handled by PAM. Thus,
<filename>/etc/login.defs</filename> is no longer used by programs
such as: <citerefentry>

</citerefentry>, <citerefentry>
