.SH "DESCRIPTION"
.PP
The
/etc/login\&.defs
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\&.
.PP
Ce fichier est un fichier texte, dont chaque ligne d\('ecrit un param\(`etre de configuration\&. Les lignes consistent en un nom et une valeur, s\('epar\('es par une espace\&. Les lignes blanches et les lignes de commentaires sont ignor\('ees\&. Les commentaires commencent par un caract\(`ere \(Fo\ \&#\ \&\(Fc, qui doit \(^etre le premier caract\(`ere non blanc de la ligne\&.
.PP
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
\fIyes\fR
or
\fIno\fR\&. An undefined boolean parameter or one with a value other than these will be given a
\fIno\fR
value\&. Numbers (both regular and long) may be either decimal values, octal values (precede the value with
\fI0\fR) or hexadecimal values (precede the value with
\fI0x\fR)\&. The maximum value of the regular and long numeric parameters is machine\-dependent\&.
.PP
Les param\(`etres de configuration suivants sont fournis\ \&:
.PP
\fBCHFN_RESTRICT\fR (string)
.RS 4
This parameter specifies which values in the
\fIgecos\fR
field of the
/etc/passwd
file may be changed by regular users using the
\fBchfn\fR
program\&. It can be any combination of letters
\fIf\fR,
\fIr\fR,
\fIw\fR,
\fIh\fR, for Full name, Room number, Work phone, and Home phone, respectively\&. For backward compatibility,
\fIyes\fR
is equivalent to
\fIrwh\fR
and
\fIno\fR
is equivalent to
\fIfrwh\fR\&. If not specified, only the superuser can make any changes\&. The most restrictive setting is better achieved by not installing
\fBchfn\fR
SUID\&.

\fBCONSOLE_GROUPS\fR (string)
.RS 4

Highest user ID number for which the lastlog entries should be updated\&. As higher user IDs are usually tracked by remote user identity and authentication services there is no need to create a huge sparse lastlog file for them\&.

Much of the functionality that used to be provided by the shadow password suite is now handled by PAM\&. Thus,
/etc/login\&.defs
is no longer used by
\fBpasswd\fR(1), or less used by
\fBlogin\fR(1), and
\fBsu\fR(1)\&. Please refer to the corresponding PAM configuration files instead\&.
