I’m using Rails 4.2.3. I’m trying to enable external authentication via DigitalOcean, using the tutorial but I”m running into some problems. I have registered my application with DigitalOcean (using the callback http://localhost:3000/users/auth/digitalocean/callback) and gotten my client ID and secret, which I have added into config/initializers/devise.rb
config.omniauth :digitalocean, “myid”, “mysecret” config.omniauth :google, “Myid”, “MySecret”
and I have added the callback to app/controllers/callbacks_controller.rb
def digitalocean @user = User.from_omniauth(request.env["omniauth.auth"]) logger.debug "user: @user" sign_in_and_redirect @user end
However, when I link to DigitalOcean from my application home page and then click on the “Authorize Application” from this page on DigitalOcaen’s site — https://cloud.digitalocean.com/v1/oauth/authorize?client_id=myid&redirect_uri=http%3A%2F%2Flocalhost%3A3000%2Fusers%2Fauth%2Fdigitalocean%2Fcallback&response_type=code&state=b97390521c4edf54c6331d849fb8597dc6c15795c0cbfe8c , I am getting this error in my log
E, [2016-01-24T14:56:26.493450 #36584] ERROR -- omniauth: (digitalocean) Authentication failure! invalid_credentials: OAuth2::Error, invalid_grant: The provided authorization grant is invalid, expired, revoked, does not match the redirection URI used in the authorization request, or was issued to another client.
What do I need to configure where to allow things to work properly?
