# Custom scopes, claims and client features
|
|
|
|
This document describes the set of OAuth2 and OpenID Connect features implemented by dex.
|
|
|
|
## Scopes
|
|
|
|
The following is the exhaustive list of scopes supported by dex:
|
|
|
|
| Name | Description |
|
|
| ---- | ------------|
|
|
| `openid` | Required scope for all login requests. |
|
|
| `email` | ID token claims should include the end user's email and if that email was verified by an upstream provider. |
|
|
| `profile` | ID token claims should include the username of the end user. |
|
|
| `groups` | ID token claims should include a list of groups the end user is a member of. |
|
|
| `offline_access` | Token response should include a refresh token. Doesn't work in combinations with some connectors, notability the [SAML connector][saml-connector] ignores this scope. |
|
|
| `audience:server:client_id:( client-id )` | Dynamic scope indicating that the ID token should be issued on behalf of another client. See the _"Cross-client trust and authorized party"_ section below. |
|
|
|
|
## Custom claims
|
|
|
|
Beyond the [required OpenID Connect claims][core-claims], and a handful of [standard claims][standard-claims], dex implements the following non-standard claims.
|
|
|
|
| Name | Description |
|
|
| ---- | ------------|
|
|
| `groups` | A list of strings representing the groups a user is a member of. |
|
|
| `email` | The email of the user. |
|
|
| `email_verified` | If the upstream provider has verified the email. |
|
|
| `name` | User's display name. |
|
|
|
|
## Cross-client trust and authorized party
|
|
|
|
Dex has the ability to issue ID tokens to clients on behalf of other clients. In OpenID Connect terms, this means the ID token's `aud` (audience) claim being a different client ID than the client that performed the login.
|
|
|
|
For example, this feature could be used to allow a web app to generate an ID token on behalf of a command line tool:
|
|
|
|
```yaml
|
|
staticClients:
|
|
- id: web-app
|
|
redirectURIs:
|
|
- 'https://web-app.example.com/callback'
|
|
name: 'Web app'
|
|
secret: web-app-secret
|
|
|
|
- id: cli-app
|
|
redirectURIs:
|
|
- 'https://cli-app.example.com/callback'
|
|
name: 'Command line tool'
|
|
secret: cli-app-secret
|
|
# The command line tool lets the web app issue ID tokens on its behalf.
|
|
trustedPeers:
|
|
- web-app
|
|
```
|
|
|
|
Note that the command line tool must explicitly trust the web app using the `trustedPeers` field. The web app can then use the following scope to request an ID token that's issued for the command line tool.
|
|
|
|
```
|
|
audience:server:client_id:cli-app
|
|
```
|
|
|
|
The ID token claims will then include the following audience and authorized party:
|
|
|
|
```
|
|
{
|
|
"aud": "cli-app",
|
|
"azp": "web-app",
|
|
"email": "foo@bar.com",
|
|
// other claims...
|
|
}
|
|
```
