## What is GitLab
|
|
|
|
From https://about.gitlab.com/what-is-gitlab/
|
|
|
|
:::note
|
|
GitLab is a complete DevOps platform, delivered as a single application. This makes GitLab unique and makes Concurrent DevOps possible, unlocking your organization from the constraints of a pieced together toolchain. Join us for a live Q&A to learn how GitLab can give you unmatched visibility and higher levels of efficiency in a single application across the DevOps lifecycle.

## Preparation
|
|
|
|
The following placeholders will be used:
|
|
|
|
- `gitlab.company` is the FQDN of the GitLab Install
|
|
- `authentik.company` is the FQDN of the authentik Install
|
|
|
|
Create an application in authentik and note the slug, as this will be used later. Create a SAML provider with the following parameters:
|
|
|
|
- ACS URL: `https://gitlab.company/users/auth/saml/callback`
|
|
- Audience: `https://gitlab.company`
|
|
- Issuer: `https://gitlab.company`
|
|
- Binding: `Redirect`
|
|
|
|
Under _Advanced protocol settings_, set a certificate for _Signing Certificate_.
|
|
|
|
## GitLab Configuration
|
|
|
|
Paste the following block in your `gitlab.rb` file, after replacing the placeholder values from above. The file is located in `/etc/gitlab`.
|
|
To get the value for `idp_cert_fingerprint`, go to the Certificate list under _Identity & Cryptography_, and expand the selected certificate.
|
|
|
|
```ruby
|
|
gitlab_rails['omniauth_enabled'] = true
|
|
gitlab_rails['omniauth_allow_single_sign_on'] = ['saml']
|
|
gitlab_rails['omniauth_sync_email_from_provider'] = 'saml'
|
|
gitlab_rails['omniauth_sync_profile_from_provider'] = ['saml']
|
|
gitlab_rails['omniauth_sync_profile_attributes'] = ['email']
|
|
gitlab_rails['omniauth_auto_sign_in_with_provider'] = 'saml'
|
|
gitlab_rails['omniauth_block_auto_created_users'] = false
|
|
gitlab_rails['omniauth_auto_link_saml_user'] = true
|
|
gitlab_rails['omniauth_providers'] = [
|
|
{
|
|
name: 'saml',
|
|
args: {
|
|
assertion_consumer_service_url: 'https://gitlab.company/users/auth/saml/callback',
|
|
# Shown when navigating to certificates in authentik
|
|
idp_cert_fingerprint: '4E:1E:CD:67:4A:67:5A:E9:6A:D0:3C:E6:DD:7A:F2:44:2E:76:00:6A',
|
|
idp_sso_target_url: 'https://authentik.company/application/saml/<authentik application slug>/sso/binding/redirect/',
|
|
issuer: 'https://gitlab.company',
|
|
name_identifier_format: 'urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress',
|
|
attribute_statements: {
|
|
email: ['http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress'],
|
|
first_name: ['http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name'],
|
|
nickname: ['http://schemas.goauthentik.io/2021/02/saml/username']
|
|
}
|
|
},
|
|
label: 'authentik'
|
|
}
|
|
]
|
|
```
|
|
|
|
Afterwards, either run `gitlab-ctl reconfigure` if you're running GitLab Omnibus, or restart the container if you're using the container.
