The group ID of the given

|
<I>GROUP</I>

|
|
<P>
|
|
The value of

|
<I>GID</I>

|
|
option is used.
|
|
<P>
|
|
Benutzer, welche die Gruppe als Hauptgruppe verwenden, werden aktualisiert, um die Gruppe als Hauptgruppe zu behalten.
|
|
<P>
|
|
Any files that have the old group ID and must continue to belong to
|
|
<I>GROUP</I>, must have their group ID changed manually.
|
|
<P>
|
|
No checks will be performed with regard to the
|
|
<B>GID_MIN</B>,
|

<B>GID_MAX</B>,

<B>Note:</B>

This option is not recommended because the password (or encrypted password) will be visible by users listing the processes.

Sie sollten sicherstellen, dass das Passwort den Passwortrichtlinien des Systems entspricht.

Apply changes in the

|

directory and use the configuration files from the
|
|
<I>PREFIX_DIR</I>
|
|
directory. This option does not chroot and is intended for preparing a cross-compilation target. Some limitations: NIS and LDAP users/groups are not verified. PAM authentication is using the host files. No SELINUX support.

<P>
|
|
|
|
The following configuration variables in
|
|
/etc/login.defs
|
|
change the behavior of this tool:
|
|
<P>
|
|
|
|
<B>MAX_MEMBERS_PER_GROUP</B> (number)
|
|
<DL COMPACT><DT id="9"><DD>
|
|
Maximum members per group entry. When the maximum is reached, a new group entry (line) is started in
|
|
/etc/group
|
|
(with the same name, same password, and same GID).
|
|
<P>
|
|
Der Standardwert ist 0, was zur Folge hat, dass die Anzahl der Mitglieder einer Gruppe nicht begrenzt ist.
|
|
<P>
|
|
Diese Fähigkeit (der aufgeteilten Gruppe) ermöglicht es, die Zeilenlänge in der Gruppendatei zu begrenzen. Damit kann sichergestellt werden, dass die Zeilen für NIS-Gruppen nicht länger als 1024 Zeichen sind.
|
|
<P>
|
|
Falls Sie eine solche Begrenzung benötigen, können Sie 25 verwenden.
|
|
<P>
|
|
Hinweis: Aufgeteilte Gruppen werden möglicherweise nicht von allen Werkzeugen unterstützt, selbst nicht aus der Shadow-Werkzeugsammlung. Sie sollten diese Variable nur setzen, falls Sie zwingend darauf angewiesen sind.
