Thinktecture Identity Server - setup external identity providers

Question

I'm following Brock's tutorial on OAuth2 identity providers: OAuth2 in Thinktecture IdentityServer : OAuth2 identity providers and I'm having problems trying to setup each provider details. I'm trying to use google and facebook.

Google: What I've done is. I've created new project, within which I've gone to APIs & auth > Credentials > Create New Client ID and then chose "Web Application" option. On "Client ID for web application" panel in "Javascript Origins" section I have pasted base URL of my IdSrv (https://somename). I have copied Client ID and Client secret and pasted both into appropriate sections in IdSrv identity provider shown in tutorial. When I run the application I get the invalid_request error from Google saying Invalid parameter value for redirect_uri: Non-public domains not allowed: https://somename/idsrv/issue/hrd/oauth2callback

In case of Facebook, I've created new App, and was trying to set "Site URL" in basic settings to https://somename, but got an alert saying "must be a URL with a valid domain." which I believe is essentially the same as what the Google error message is saying

My question is: How can I deploy a test version of my IdSrv then? I just want a quick and simple environment for testing purposes for now. Am running the IdSrv in my local IIS, was following Dominick installation tutorial video Thinktecture IdentityServer v2 Tutorial: Installation

Answer 1

When we setup IdentityServer for local testing we configure it to run under IIS with a custom host name and then setup a entry in the local hosts file. To google this should appear as a public URL.

Answer 2

An easier approach is to use one of the localhost DNS services that exist.

For example, whatever.vcap.me resolves to 127.0.0.1 as does production.vcap.me, staging.vcap.me and development.vcap.me.
