centos:ldap:annonbind

Konfiguration auf Clientseite zur Client-Authentification via anonymous bind

OpenLDAP Logo

Bei den betreffenden Clients wollen wir nun die Authentifizierung der einzelnen User nicht mehr gegen die lokale /etc/shadow laufen lassen, denn dazu müssten wir nun auf jedem Host die User manuell (nach)pflegen. Schließlich sollen die User, egal an welchem Host sie sich anmelden, immer auch das gleiche Passwort benutzen können. Nicht zuletzt aus diesem Gründen, haben wir uns für einen zentralen OpenLDAP-Server entschieden.

Die nachfolgende Beschreibung nutzt bei der Realisierung keinen System Security Services Daemon sssd. Auf diesen werden wir noch in einem separatem Kapitel detailliert eingehen.

Installation

Wie bereits erwähnt, verzichten wir im ersten Schritt auf den System Security Services Daemon. Als erstes deinstallieren wir den sssd, sofern dieser zuvor installiert worden war. 

 # yum remove sssd

Auf der Clientseite benötigen wir nachfolgende Pakete, die wir bei Bedarf mit Unterstützung von YUM nachinstallieren.

  • openldap
  • openldap-clients
  • pam_ldap
  • nss-pam-ldapd
  • pam
  • glibc
  • authconfig
 # yum install openldap openldap-clients pam_ldap nss-pam-ldapd pam glibc authconfig -y

Was uns die einzelnen Pakete mit ins System bringen, erkunden wir bei Bedarf mit dem Aufruf mit dem Aufruf von rpm -qil.

Summary     : LDAP support libraries
Description :
OpenLDAP is an open source suite of LDAP (Lightweight Directory Access
Protocol) applications and development tools. LDAP is a set of
protocols for accessing directory services (usually phone book style
information, but other information is possible) over the Internet,
similar to the way DNS (Domain Name System) information is propagated
over the Internet. The openldap package contains configuration files,
libraries, and documentation for OpenLDAP.

Summary     : The GNU libc libraries
Description :
The glibc package contains standard libraries which are used by
multiple programs on the system. In order to save disk space and
memory, as well as to make upgrading easier, common system code is
kept in one place and shared between programs. This particular package
contains the most important sets of shared libraries: the standard C
library and the standard math library. Without these two libraries, a
Linux system will not function.

Authconfig is a command line utility which can configure a workstation
to use shadow (more secure) passwords.  Authconfig can also configure a
system to be a client for certain networked user information and
authentication schemes.

Konfiguration

Die Konfiguration unseres Clients nehmen wir am einfachsten mit Hilfe des Programmes authconfig aus dem RPM-Paket authconfig-gtk vor. Hierzu rufen wir authconfig mit den nötigen Optionen für unsere (Test-)Umgebung auf.

  • disablemd5 MD5 Passworter abschalten
  • passalgo Definition des Passworthash-Algoritmuses
  • enablemkhomedir Homedirectory beim ersten Login eines neuen Users automatisch anlegen
  • enableldap LDAP User Informationen aktivieren
  • enableldapauth LDAP Authentifizierung aktivieren
  • ldapserver LDAP Servername oder URI Definition
  • ldapbasedn LDAP Basde DN Definition
  • update Update der Konfigurationsdateien mit den gesetzten Werten.

Eine ausführliche Beschreibung der optionen erhält man übder die Manpage von authconfig oder beim Aufruf der Option –help. 

 # authconfig --help

Wir Konfigurieren nun also unsere LDAP-Client-Authentifizierung wie folgt. 

 # authconfig --disablemd5 --passalgo=sha256 --enablemkhomedir --enableldap --enableldapauth --ldapserver=ldap.dmz.nausch.org --ldapbasedn="dc=nausch,dc=org" --update
 nslcd starten:                                             [  OK  ]
 oddjobd starten:                                           [  OK  ]

Die einzelnen Konfigurationsdateien, die mit dem vorgenannten Programmaufruf angepasst wurden, werden wir uns im Detail betrachten, ggf. anpassen und mit Bearbeitungsvermerken versehen, damit wir später noch nachvollziehen können, welche Änderungen im Detail notwendig waren um die LDAP Client Authentifizierung aktiviert werden konnte.

Zur Dokumentation und ggf. spätere weitere Dokumentationsschritte versehen wir optional alle Änderungen mit einem Kommntar, ala: # Django : Datum [optionaler Grund].

authconfig

In der Konfigurationsdatei /etc/sysconfig/authconfig setzen wir die beiden folgenden Werte von no auf yes:

  • USELDAP=yes (LDAP-Authentifizierung aktivieren.)
  • FORCELEGACY=yes (CentOS 6 nutzt standardmäßig TLS für die LDAP-Authentifizierung. Mit diesem Schalter wird diese Voreinstellung deaktiviert und die die unverschlüsselte Kommunikation mit dem LDAP-Server erzwungen.)

Zur Bearbeitung der Konfigurationsdatei nutzen wir wie so oft immer unseren Editor der Wahl vim. 

 # vim /etc/sysconfig/authconfig
/etc/sysconfig/authconfig
USEMKHOMEDIR=no
USEPAMACCESS=no
CACHECREDENTIALS=yes

In der Konfigurationsdatei /etc/pam.d/system-auth tragen wir folgende Daten nach:

  • passwd: files ldap
  • shadow: files ldap
  • group: files ldap
  • netgroup: ldap
  • automount: files ldap

Zur Bearbeitung der Konfigurationsdatei nutzen wir wie so oft immer unseren Editor der Wahl vim. 

 # vim /etc/nsswitch.conf
/etc/nsswitch.conf
#
# /etc/nsswitch.conf
#
# An example Name Service Switch config file. This file should be
# sorted with the most-used services at the beginning.
#
# The entry '[NOTFOUND=return]' means that the search for an
# entry should stop if the search in the previous entry turned
# up nothing. Note that if the search failed due to some other reason
# (like no NIS server responding) then the search continues with the
# next entry.
#
# Valid entries include:
#
#       nisplus                 Use NIS+ (NIS version 3)
#       nis                     Use NIS (NIS version 2), also called YP
#       dns                     Use DNS (Domain Name Service)
#       files                   Use the local files
#       db                      Use the local database (.db) files
#       compat                  Use NIS on compat mode
#       hesiod                  Use Hesiod for user lookups
#       [NOTFOUND=return]       Stop searching if not found so far
#
 
# To use db, put the "db" in front of "files" for entries you want to be
# looked up first in the databases
#
# Example:
#passwd:    db files nisplus nis
#shadow:    db files nisplus nis
#group:     db files nisplus nis

automatischer Systemstart des nslc-Dämon

Damit nun beim nächsten Start des Systems der notwendige naming services LDAP client daemon kurz nslcd mit gestartet wird, versetzen wir das Startscript in den Modus „on“. 

 # chkconfig nslcd on

Den Status überprüfen wir bei Bedarf mittels: 

 # chkconfig --list | grep nslcd
 nslcd           0:off   1:off   2:on    3:on    4:on    5:on    6:off

Zum Abschluss unserer Konfiguration starten wir nun unseren CentOS 6 Client einmal durch. 

 # reboot

LDAP Abfrage

Zur Abfrage eines LDAP-Users können wir folgenden Aufruf verwenden: 

 $ ldapsearch -x -LLL -H ldap://ldap.dmz.nausch.org -b "dc=nausch,dc=org" "uid=bigchief"
dn: uid=bigchief,ou=People,dc=nausch,dc=org
uid: bigchief
cn: BigChief
objectClass: account
objectClass: posixAccount
objectClass: top
objectClass: shadowAccount
shadowLastChange: 15274
shadowMin: 0
shadowMax: 99999
shadowWarning: 7
loginShell: /bin/bash
uidNumber: 501
gidNumber: 501
homeDirectory: /home/bigchief
gecos: BigChief

LDAP-Abfrage mit dem User Django aber mit falschem Passwort: 

 $ ldapsearch -x -LLL -H ldap://ldap.dmz.nausch.org -b "dc=nausch,dc=org" "uid=django" -W -D "uid=django,ou=People,dc=nausch,dc=org"
Enter LDAP Password: 
ldap_bind: Invalid credentials (49)

LDAP-Abfrage mit dem User Django aber mit richtigem Passwort: 

 $ ldapsearch -x -LLL -H ldap://ldap.dmz.nausch.org -b "dc=nausch,dc=org" "uid=django" -W -D "uid=django,ou=People,dc=nausch,dc=org"
Enter LDAP Password:

Clienttest

Die erfolgreiche Konfiguration unseres Rechners überprüfen wir so:

  1. Mit getent lassen wir uns die Informationen eines Users anzeigen, der sowohl in der /etc/shadow wie auch im zentralen LDAP-Verzeichnisdienst hinterlegt ist. Wenn alles gut gelaufen ist, werden uns zwei Einträge präsentiert. 

    $ getent passwd | grep django
django:x:500:500::/home/django:/bin/bash
django:x:500:500:Django:/home/django:/bin/bash
  2. Als nächstes wählen wir einen Nutzer der nur im LDAP-Verzeichnisdienst einen Account hat, nicht aber auf der lokalen Maschine. 

    $ getent passwd | grep bigchief
bigchief:x:501:501:BigChief:/home/bigchief:/bin/bash
  3. Dann melden wir uns nun an unserem Client als ein Benutzer an, der lokal auf der Maschine nicht existiert, werden wir beim Login nach dem Passwort gefragt, welches gegen den zentralen OpenLDAP-Server verifiziert wird. Ist das Passwort richtig wird auch gleich das zugehörige Nutzer-Homeverzeichnis angelegt. 

    [django@vml010008 ~]$ su - ruben
    Password:
    Creating directory '/home/ruben'.
