OpenID Connect Configuration

OpenID Connect is supported in Dependency-Track 4.0.0 and above

In the context of OAuth2 / OIDC, Dependency-Track’s frontend acts as client while the API server acts as resource server (see OAuth2 roles). Due to this, the frontend requires additional configuration, which is currently only supported when deploying it separately from the API server. Refer to the Configuration and Docker deployment pages for instructions. “Classic” Dependency-Track deployments using solely the WAR or executable WAR are not supported!

If configured properly, users will be able to sign in by clicking the OpenID button on the login page:

Before v4.3.0, Dependency-Track exclusively used the /userinfo endpoint of the IdP to get user information.
Since v4.3.0, ID tokens are validated and evaluated as well. They even take precedence over /userinfo,
which means that Dependency-Track will no longer request the /userinfo endpoint if all required claims
are present in the ID token’s payload already.

Example Configurations

Generally, Dependency-Track can be used with any identity provider that implements the OpenID Connect standard. Multiple identity providers have been tested, the following are some example configurations that are known to work. Note that some providers may not support specific features like team synchronization, or require further configuration to make them work. If you find that the provider of your choice does not work with Dependency-Track, please file an issue.

For a complete overview of available configuration options for both backend and frontend, please refer to the Configuration page.

Auth0

API server	Frontend
alpine.oidc.enabled=true
alpine.oidc.client.id=9XgMg7bP7QbD74TZnzZ9Jhk9KHq3RPCM	OIDC_CLIENT_ID=9XgMg7bP7QbD74TZnzZ9Jhk9KHq3RPCM

alpine.oidc.team.synchronization=true*

* Requires additional configuration

GitLab (gitlab.com)

API server	Frontend
alpine.oidc.enabled=true
alpine.oidc.client.id=ff53529a3806431e06b2930c07ab0275a9024a59873a0d5106dd67c4cd34e3be	OIDC_CLIENT_ID=ff53529a3806431e06b2930c07ab0275a9024a59873a0d5106dd67c4cd34e3be

alpine.oidc.username.claim=nickname
alpine.oidc.user.provisioning=true
alpine.oidc.teams.claim=groups
alpine.oidc.team.synchronization=true

gitlab.com currently does not set the required CORS headers, see GitLab issue #209259.
For on-premise installations, this could be fixed by setting the required headers via reverse proxy.

Keycloak

API server	Frontend
alpine.oidc.enabled=true
alpine.oidc.client.id=dependency-track	OIDC_CLIENT_ID=dependency-track
alpine.oidc.issuer=https://auth.example.com/auth/realms/example	OIDC_ISSUER=https://auth.example.com/auth/realms/example
alpine.oidc.username.claim=preferred_username
alpine.oidc.user.provisioning=true
alpine.oidc.teams.claim=groups*
alpine.oidc.team.synchronization=true*

* Requires additional configuration, see Example setup with Keycloak

Example setup with Keycloak

The following steps demonstrate how to setup OpenID Connect with Keycloak. Most settings should be applicable to other IdPs as well.

This guide assumes that:

the Dependency-Track frontend has been deployed to https://dependencytrack.example.com

a Keycloak instance is available at https://auth.example.com

the realm example has been created in Keycloak

Configure the client as shown below:
- Client ID: dependency-track
- Client Protocol: openid-connect
- Access Type: public
- Standard Flow Enabled: ON
- Valid Redirect URIs: https://dependencytrack.example.com/static/oidc-callback.html*
- The trailing * is required when using the frontend v1.3.0 or newer, in order to support post-login redirects
- Web Origins: https://dependencytrack.example.com
To be able to synchronize team memberships, create a protocol mapper that includes group memberships as groups in the /userinfo endpoint:
- Mapper Type: Group Membership
- Token Claim Name: groups
- Add to userinfo: ON (optional for Dependency-Track v4.3.0 and newer)
- Add to ID token: ON (for Dependency-Track v4.3.0 and newer)
Create some groups, e.g. DTRACK_ADMINS and DTRACK_USERS:

Verify that all required claims are present in the /userinfo endpoint

Acquire an access token for a user and call /userinfo with it

You can temporarily set Direct Access Grants Enabled to ON in the client settings to enable the Resource Owner Password Credentials Grant

$ ACCESS_TOKEN=$(curl https://auth.example.com/auth/realms/example/protocol/openid-connect/token \
 -d "client_id=dependency-track" \
 -d "grant_type=password" \
 -d "username=demo-user" \
 -d "password=demo-pass" \
 | jq -r .access_token)
$ curl https://auth.example.com/auth/realms/example/protocol/openid-connect/userinfo \
 -H "Authorization: Bearer $ACCESS_TOKEN"

The response should look similar to this:

{
  "groups": ["DTRACK_USERS"],
  "sub": "290e5d27-25d2-414c-a04c-5d03cd0e1db8",
  "email_verified": true,
  "preferred_username": "demo-user",
  "email": "[email protected]"
}

Configure OIDC for both backend and frontend of Dependency-Track, as demonstrated below for a docker-compose deployment:

 version: "3"

 services:
   dtrack:
     image: dependencytrack/dependency-track
     environment:
       # ...
       - "ALPINE_OIDC_ENABLED=true"
       - "ALPINE_OIDC_CLIENT_ID=dependency-track"
       - "ALPINE_OIDC_ISSUER=https://auth.example.com/auth/realms/example"
       - "ALPINE_OIDC_USERNAME_CLAIM=preferred_username"
       - "ALPINE_OIDC_TEAMS_CLAIM=groups"
       - "ALPINE_OIDC_USER_PROVISIONING=true"
       - "ALPINE_OIDC_TEAM_SYNCHRONIZATION=true"

   dtrack-frontend:
     image: dependencytrack/frontend
     environment:
       # ...
       - "OIDC_ISSUER=https://auth.example.com/auth/realms/example"
       - "OIDC_CLIENT_ID=dependency-track"

Login to Dependency-Track as admin and navigate to Administration -> Access Management -> OpenID Connect Groups
- Create groups with names equivalent to those in Keycloak
- Add teams that the groups should be mapped to
Use the OpenID button on the login page to sign in with a Keycloak user that is member of at least one of the configured groups. Navigating to Administration -> Access Management -> OpenID Connect Users should now reveal that the user has been automatically provisioned and team memberships have been synchronized:

Dependency-Track associates every OpenID Connect user with their subject identifier (sub claim of the access token) upon first login. If a user with the same name but a different subject identifier attempts to log in via OIDC, Dependency-Track will refuse to authenticate that user. This is done to prevent account takeovers, as some identity providers allow users to change their usernames. Also, uniqueness of usernames is not always guaranteed, while the uniqueness of subject identifiers is.
