JWT OmniAuth provider (FREE SELF)

To enable the JWT OmniAuth provider, you must register your application with JWT. JWT provides you with a secret key for you to use.

1. On your GitLab server, open the configuration file.

   For Omnibus GitLab:

   sudo editor /etc/gitlab/gitlab.rb
   

   For installations from source:

   cd /home/git/gitlab
   sudo -u git -H editor config/gitlab.yml
   

2. See Configure initial settings for initial settings.

3. Add the provider configuration.

   For Omnibus GitLab:

   gitlab_rails['omniauth_providers'] = [
     { name: "jwt",
       label: "Provider name", # optional label for login button, defaults to "Jwt"
       args: {
         secret: "YOUR_APP_SECRET",
         algorithm: "HS256", # Supported algorithms: "RS256", "RS384", "RS512", "ES256", "ES384", "ES512", "HS256", "HS384", "HS512"
         uid_claim: "email",
         required_claims: ["name", "email"],
         info_map: { name: "name", email: "email" },
         auth_url: "https://example.com/",
         valid_within: 3600 # 1 hour
       }
     }
   ]
   

   For installation from source:

   - { name: 'jwt',
       label: 'Provider name', # optional label for login button, defaults to "Jwt"
       args: {
         secret: 'YOUR_APP_SECRET',
         algorithm: 'HS256', # Supported algorithms: 'RS256', 'RS384', 'RS512', 'ES256', 'ES384', 'ES512', 'HS256', 'HS384', 'HS512'
         uid_claim: 'email',
         required_claims: ['name', 'email'],
         info_map: { name: 'name', email: 'email' },
         auth_url: 'https://example.com/',
         valid_within: 3600 # 1 hour
       }
     }
   

   NOTE: For more information on each configuration option refer to the OmniAuth JWT usage documentation.

4. Change YOUR_APP_SECRET to the client secret and set auth_url to your redirect URL.

5. Save the configuration file.

6. For the changes to take effect:

   • If you installed via Omnibus, reconfigure GitLab.
   • If you installed from source, restart GitLab.

On the sign in page there should now be a JWT icon below the regular sign in form. Select the icon to begin the authentication process. JWT asks the user to sign in and authorize the GitLab application. If everything goes well, the user is redirected to GitLab and signed in.
