Authentication: SSO with OpenID Connect

Linkurious Enterprise supports any OpenID Connect compatible provider as external authentication providers.

What is OpenID Connect?

OpenID Connect is an identity layer on top of the OAuth2 protocol. It allows applications (like Linkurious Enterprise) to verify the identity of End-User based on the authentication performed by an Authorization Server, as well as to obtain basic profile information about the End-User in an interoperable manner.

Configuration

To set up Linkurious Enterprise authentication with an OpenID Connect provider, you need to obtain the following parameters from the provider:

• authorizationURL, e.g. https://accounts.google.com/o/oauth2/v2/auth
• tokenURL, e.g. https://www.googleapis.com/oauth2/v4/token
• clientID, e.g. 1718xxxxxx-xxxxxxxxxxxxxxxx.apps.googleusercontent.com
• clientSecret, e.g. E09dQxxxxxxxxxxxxxxxxSN

Example access.oauth2 configuration with any OpenID Connect provider:

"access": {
  // [...]
  "oauth2": {
    "enabled": true,
    "provider": "openidconnect",
    "authorizationURL": "https://accounts.google.com/o/oauth2/v2/auth",
    "tokenURL": "https://www.googleapis.com/oauth2/v4/token",
    "clientID": "XXXXXXXXXX-XXXXXXXXXXXXXXXX.apps.googleusercontent.com",
    "clientSecret": "XXXXXXXXXXXXXXXXXXXXXXX"
  }
}

OAuth2 redirect URL

The OAuth2 redirect URL of Linkurious Enterprise is the following: http(s)://HOST:PORT/api/auth/sso/return.

Group mapping in OIDC

To set up group mapping in OpenID Connect is necessary to specify additional configuration keys:

• openidconnect.userinfoURL, e.g. https://XXXXXXXXXX.oktapreview.com/oauth2/v1/userinfo
• openidconnect.scope, e.g. openid profile email groups
• openidconnect.groupClaim, e.g. groups

For example if you want to set up OIDC with Okta:

"access": {
  // [...]
  "oauth2": {
    "enabled": true,
    "provider": "openidconnect",
    "authorizationURL": "https://XXXXXXXXXX.oktapreview.com/oauth2/v1/authorize",
    "tokenURL": "https://XXXXXXXXXX.oktapreview.com/oauth2/v1/token",
    "clientID": "XXXXXXXXXXXXXXXXXXXXXXX",
    "clientSecret": "XXXXXXXXXXXXXXXXXXXXXXX",
    "openidconnect": {
      "userinfoURL": "https://XXXXXXXXXX.oktapreview.com/oauth2/v1/userinfo",
      "scope": "openid profile email groups",
      "groupClaim": "groups"
    }
}
