Configuring a SAML IDP with LDAP as authentication source

dthLeave a comment

In this setup, the SAML IDP will be available at example.com/auth and we will use the ldap server configured in this post.

Start by moving to the directory above the DocumentRoot for the domain. Let’s say that it is /var/www/example.com, so

cd /var/www/

Download the latest simplesamlphp version

wget https://simplesamlphp.org/res/downloads/simplesamlphp-1.14.4.tar.gz && tar xvfz simplesamlphp-1.14.4.tar.gz

This will be a minimal setup. It’s a good idea to start by doing an update and upgrade on your system. In debian, use:

apt-get update && apt-get upgrade

Install the packages (set and confirm admin password)

apt-get install slapd ldap-utils phpldapadmin

Then vim /etc/ldap/ldap.conf and include:

BASE dc=example,dc=net
URI ldap://127.0.0.1
