The
/etc/login.defs
file defines the site-specific configuration for the shadow login
suite. This file is required. Absence of this file will not prevent
system operation, but will probably result in undesirable operation.
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, seperated 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.
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 ``yes'' or ``no''. An undefined
boolean parameter or one with a value other than these will be given
a ``no'' value. Numbers (both regular and long) may be either decimal
values, octal values (precede the value with ``0'') or hexadecimal
values (precede the value with ``0x''). The maximum value of the
regular and long numeric parameters is machine-dependant.
The following configuration items are provided:
