Overview
This PR adds support for
prompt=noneas described in the specs section 3.1.2.1.What this PR does / why we need it
Currently dex lacks support for the
prompt=noneparameter. Thoughpromptis an optional parameter in the request, if it is set tononethe IdP must not show any login mask or other UIs. Instead it should either return a new token if the session is still valid or return an error (which is always the case for dex, as there are no sessions).This PR adds support for
prompt=nonein a way which will check for the existence of the parameter and the value and if that is the case, it always returns alogin_requirederror.
