I would like to add an optional parameter to the /session/sso path that the controller would add onto the IDP request URL. The purpose is to tell the IDP which authentication flow to initiate, i.e. social login or local login. I can’t do that without giving some kind of signal to the IDP as part of the initial Discourse SSO redirect.
I’m thinking something like idp_param as the optional parameter, i.e.:
/session/sso?return_path=/&idp_param=fb
Would there be any objection to this and a pull request?
The reason for this is I want to create a big banner that invites anonymous visitors to sign in using one of the up-stream social providers configured on our IDP as I think the single ‘Login’ button Discourse provides is not inviting or informative enough.
Current mock-up where the two social buttons would add a idp_param to the URL:
