LDAP authentication
From MoodleDocs
This document describes how to set up LDAP authentication in Moodle. You can find a Basic Scenario, where everything is simple and straightforward, and that should be enough for most installations. If your installation is a little bigger and you are using multiple LDAP servers, or multiple locations for your users in your LDAP tree, then have a look at the Advanced Scenarios.
Basic Scenario
Assumptions
- Your Moodle site is located at http://your.moodle.site/
- You have configured your PHP installation with the LDAP extension. It is loaded and activated, and it shows when you go to http://your.moodle.site/admin/phpinfo.php (logged in as user 'admin').
- Your LDAP server has 192.168.1.100 as its IP address.
- You are not using LDAP with SSL (also known as LDAPS) in your settings. This might prevent certain operations from working (e.g., you cannot update data if you are using MS Active Directory -- MS-AD from here on --), but should be OK if you just want to authenticate your users.
- You are using a single domain as the source of your authentication data in case you are using MS-AD (more on this in the Appendices).
- You are using a top level distinguished name (DN) of dc=my,dc=organization,dc=domain as the root of your LDAP tree.
- You have a non-privileged LDAP user account you will use to bind to the LDAP server. This is not necessary with certain LDAP servers, but MS-AD requires this and it won't hurt if you use it even if your LDAP server doesn't need it. Make sure this account and its password don't expire, and make this password as strong as possible. Remember you only need to type this password once, when configuring Moodle, so don't be afraid of making it as hard to guess as possible. Let's say this user account has a DN of cn=ldap-user,dc=my,dc=organization,dc=domain, and password hardtoguesspassword.
- All of your Moodle users are in an organizational unit (OU) called moodleusers, which is right under you LDAP root. That OU has a DN of ou=moodleusers,dc=my,dc=organization,dc=domain.
