How-To connect FreeIPA LDAP with GitLab

Instructions

This guide assumes that you have configured FreeIPA (default) and GitLab (Omni).

Set-up

Here’s what works:

  • name, username, password
  • sync updates from LDAP
  • email should be set after first login via LDAP

1) FreeIPA

  1. Add a new user, ex.: ‘crowd’ and assign a password
  2. Make sure the user is in the group ‘ipausers’

2) GitLab

Open the config

nano /etc/gitlab/gitlab.rb

and look for the following section, and adjust accordingly.

gitlab_rails['ldap_enabled'] = true
gitlab_rails['ldap_servers'] = YAML.load <<-'EOS'
  main: # 'main' is the GitLab 'provider ID' of this LDAP server
    label: 'LDAP'
    host: 'ipa.domain.com'
    port: 389
    uid: 'uid'
    bind_dn: 'uid=[new IPA user, ex.: crowd],cn=users,cn=accounts,dc=domain,dc=com'
    password: '[password of new IPA user]'
    encryption: 'plain' # "start_tls" or "simple_tls" or "plain"
    verify_certificates: true
    base: 'dc=domain,dc=com'
    attributes:
      username: ['uid']
      email: ['mail']
      name: 'displayName'
      first_name: 'givenName'
      last_name: 'sn'
EOS

and run gitlab-ctl reconfigure to make sure the settings take effect.

3) Login to GitLab via LDAP

  1. Select ‘LDAP’ on the login screen
  2. Enter your username, not email
  3. After successful login, enter your Email in the profile field

What’s next?

  1. Connect FreeIPA LDAP with Atlassian Crowd
  2. Configure FreeIPA LDAP with Matrix
  3. Configure FreeIPA with GitLab LDAP - You are here
  4. Jira 1-click installation script (MYSQL, HTTPS, NGINX reverse)
  5. Confluence 1-click installation script (MYSQL, HTTPS, NGINX reverse)
