This is a text-only version of the following page on https://raymii.org: --- Title : Gitlab Active Directory LDAP Authentication Author : Remy van Elst Date : 28-05-2013 URL : https://raymii.org/s/tutorials/Gitlab_and_Active_Directory_LDAP_Authentication.html Format : Markdown/HTML --- Gitlab is a self hosted git based source control application similar to Github, written in Ruby on Rails. It is used by many organisations and is a wonderfull piece of software. It supports LDAP Authentication (via the OmniAuth Gem), but it is tricky to set up with Active Directory and Windows Server 2003/2008/2012. This tutorials shows you how to set up Gitlab to authenticate against Active Directory LDAP.

Consider sponsoring me on Github. It means the world to me if you show your appreciation and you'll help pay the server costs.

You have to have a working Gitlab installation for this. It is tested with Gitlab 3 and up to 5.2, with an Active Directory 2008 env, and a Mixed 2008 & 2003 AD. Gitlab is installed on a Ubuntu box. First create a user in the Active Directory. My CN is Users, and my user is named `gitlab`. It does not have any special permissions, it is just a normal user. Note the Full Name you use, in my example it is "Gitlab LDAP". See the image below for an example: ![windows-gitlab][2] Now go to your Gitlab server, log in and become the git user: sudo su - git And edit the `~/gitlab/config/gitlab.yml` file. (Assuming you followed the official installation guide, otherwise adapt path.). The relevant LDAP section should contain this: ldap: enabled: true host: 'pdc1.domain.tld' base: 'CN=Users,DC=Domain,DC=tld' port: 389 uid: 'sAMAccountName' method: 'plain' # or "ssl" bind_dn: 'CN=Gitlab LDAP,CN=Users,DC=Domain,DC=tld' password: 'example_password' It took me a while to find the correct `bind_dn` and `base_dn`. It appears that they are capital sensitive, `cn=Users` would not work, but `CN=Users` does. Also, the `bind_dn` does not use the users email address, but the `Display Name`. So `CN=gitlab@domain.tld` does not work, but `CN=Gitlab LDAP` does. Hope this helps you setting up Gitlab with LDAP auth. More info on Gitlab can be found on their website: .
