Authorization Code Flow

Authenticator handling authorization code flows in OIDC.

About

No identification is done by this authenticator. It acts as a controller for issuing Json Web Tokens (JWT). Typically this authenticator is the first point of contact coming from an OpenID Connect Relying Party, requesting identification.

This authenticaton controller can be considered a start and end touch point. The main purpose is to handle OpenID Connect specifics.

Actual user identification is done elsewhere.

When using this authenticator, the ID token is fetched from the token endpoint.

Configuration

Authenticator Type: OIDCAuthCodeFlow

Common Authenticator configuration can be found here.

NOTE: id- & access-token claims can be configured globally on the authenticator OR for each relying party. Claims configured on the relying party trumps the global values.

Logging

On a successful authentication, an event is logged containing the following:

• WEB_100101

• IDENTIFIER (user traceid)

• DESTINATION_SERVICE_NAME (redirect URI)

• SOURCE_ADDRESS (user IP address)

Data sent to PIPE

All data put into the shared authentication state along with the HTTP headers are exposed and sent into the pipe.

Data put into the state by this authenticator is:

OIDC request data

Expected data from PIPE

In order to use data from PIPE the response must contain one item. All data from that item will be available when creating the ID token and access token.

Available data for ID_token and Access Token claims

Data is extracted with the help of expansions.

The following scopes are available:

Scope	Description	Example
request	The current authentication request including HTTP headers and params	{{{request.nonce}}}
item	Item properties AND the current authentication state (includes both local and global properties).	{{{item.mail}}}
session	The current session.	{{{session.sub}}}
