LDAP Wrapper for ChurchTools v2.1

This software acts as an LDAP server for ChurchTools >= 3.25.0

This software was tested in a common environment, yet no warranties of any kind!

Installation

Node.js is required to run this software. http://nodejs.org/

Node.js install

Run the install.sh script as root user. It will

• run "npm install" to install required Node.js dependencies for the server
• create a new user "ctldap" to run the server with limited privileges
• create the configuration file, asking for a reset if it already exists
• [new config or reset] ask for the ChurchTools domain (and directory)
• [new config or reset] ask for the ChurchTools API user credentials and insert them into the config file
• [new config or reset] insert a secure random LDAP root user password into the config file
• [new config or reset] offer to customize the config file
• optionally adapt and create the ctldap.sh file in /etc/init.d and call "update-rc.d ctldap.sh defaults"

ctldap.sh remarks:

The file "ctldap.sh" contains a shell script for (re)starting ctldap.sh with Node.js as a background service, redirecting all output to the system log with systemd-cat. The logs can be reviewed with the shell command journalctl -t ctldap. See https://wiki.ubuntuusers.de/systemd/journalctl/ for further options.

The script will attempt to create/remove an iptables NAT rule on start/stop in order to redirect traffic from a standard LDAP port (< 1024) to ldap_port without root.

It can be used to start/stop the service manually, but will not work correctly without root privileges!

Usage: ctldap.sh {start|stop|status|restart}

If you don't have root privileges:

• run npm install manually or otherwise trigger the installation of required dependencies
• copy "ctldap.example.config" to "ctldap.config" and adjust the required settings accordingly
• register "ctldap.js" to be run by Node.js, or start the server directly by executing node ctldap.js

Usage

The LDAP DNs depend on your configuration. Let's assume the following configuration:

ldap_user=root
ldap_password=0a1b2c3d4e5f6g7h8i9j
ldap_base_dn=churchtools

For this configuration, the

• admin DN for initial binding is cn=root,ou=users,o=churchtools
• password for initial binding is 0a1b2c3d4e5f6g7h8i9j
• users are found in the organizational unit ou=users,o=churchtools
• groups are found in the organizational unit ou=groups,o=churchtools
