Nun noch die. env erweitern. write ist hier der gruppenname

Aufrufen LDAP und co:

  • phpLDAPadmin: https://localhost:6443
    Benutzername aus unserem Beispiel : cn=admin,dc=example,dc=local
    Passwort aus unserem Beispiel : admin

    grafik.png



  • ldap-carddav WebDAV/CardDAV: http://localhost/ldap-carddav/
    Die Benutzer dazu werden im LDAP Webgui angelegt, dazu ein ein eigenes Kaptitel

Datenbank initialiseren

docker-compose exec carddav /bin/bash
sqlite3 /var/www/html/ldap-carddav/data/cards.db < /var/www/html/ldap-carddav//sql/sqlite/ddl.sql
php /var/www/html/ldap-carddav/src/App/syncdb.php init

Danach vom conatiner wieder abmelden und chmod 777 über die card.db

chown www-data:www-data -R /var/www/html/ldap-carddav/data

PHP ini Änderungen durchführen und neu mit der Datenbank  synchroniesieren:

Wenn die PHP geändert wird um zum Beispiel Felder hinzugefügt werden, muss ide Datenbank neu initialisert werden.

docker-compose exec carddav /bin/bash
php /var/www/html/ldap-carddav/src/App/syncdb.php

Ausgabe:

Nun den benutzer im carddav Backend anlegen, nicht im ldap, das haben wir gerade getan.

docker-compose exec carddav /bin/bash
php /var/www/html/ldap-carddav/src/App/syncdb.php

Fehlersuche:

Sollte Verbindung nicht zustande kommen, dann mal in die Apache2 log schauen.
Im container anmelden

Testen ob ein Objekt sich ändern lässt

ldapmodify -x -D "cn=admin,dc=example,dc=local" -w admin -H ldap://ldap


Einfügen und dann strg+d drücken

dn: cn=shacker,dc=example,dc=local
changetype: modify
replace: mail
mail: test@example.org

Ein komplettes Objekt ausgeben

ldapsearch -x \
  -D "cn=admin,dc=example,dc=local" \
  -w admin \
  -b "cn=Wolf\, SDaniel,dc=example,dc=local" \
  -LLL

Wenn syncdb.php ohne Probleme ausgeführt werden kann, liegt es nicht an Dateirechten bei root, sondern bei www-datat user.
wir werden das Verzeichnis nochmal neu mit rechten vergeben.

In den Container einloggen

 docker-compose exec carddav /bin/bash

Dnn rechte vergeben

chown www-data:www-data -R /var/www/html/ldap-carddav/data

Ansonsten schauen wir uns mal an mit welchen umser der apache2 ausgeführt wird

ps aux | grep apache
