Once the authorization provider has cleared the user, the browser
is returned here with a code. This function takes that code and
checks it with the authorization provider to prove that it is valid,
and get a bit more information about the user (which we don't use).
A token is generated and given to the user, and the authorization info
retrieved above is stored against this token. Later, when a client
connects with this token, it is assumed to be a valid user.
:return: A display of the authentication token to use in the client. If
OIDC is not configured, raises a NotImplementedException.
