I've added the client id and secret to the yml configuration file, but it's not working. When I try to login with one of the providers, it redirects me to a blank page with the message 'cannot POST /signin/google', if I try to login with Google, for example. I generated a monolith application with JWT authentication and social login feature (I'm using Angular 2+).
Maybe you should check https://console.developers.google.com/apis/credentials and set properly your Authorised JavaScript origins and Authorised redirect URIs. First one should be set to just for example http://localhost and second one must contain several entries for example
http://localhost:8080
http://localhost:8080/signin
http://localhost:8080/signin/google

I'm trying to use Keycloak (13.0.1) as an identity broker. I have an iOS app that uses keycloak to log in via an OIDC identity provider, and then use the token to access a spring-boot backend.
My issue is that I simply can't get the keycloak logout to also log the user out of the Identity Provider session.
I've spent days googling this and looking at both stackoverflow and the keycloak discourse page and git repo, but I couldn't find an answer to my specific issue.
Using the postman to test, the first time I click "Get New Access Token":
It successfully redirects me to the identity provider login page (I use the keycloak hint to bypass the initial keycloak login page). Pressing the button again will skip the IDP login and give me the token directly. How convenient, or so I thought...
The problem is that when I use keycloak's /logout endpoint to invalidate the refresh token:
And it successfully returns 204, when I click "Get new access token" again, it skips the login form and gives me the token directly, so there is effectively no way to logout the user and then login with a different user. The only way to bypass this is to manually click the "clear all cookies" button.
Here is my IDP configuration:
Also note that, in the keycloak admin guied it is specified that keycloak should be logging out of the IDPs when a logout is triggered, so it doesn't seem like I should be making any special configs:
https://www.keycloak.org/docs/latest/server_admin/#identity-broker-logout
IMPORTANT EDIT:
I marked this question as solved and the solution is correct, but I also needed to turn off the IDP "backchannel logout", because our corporate SSO doesn't like it. Keycloak seems to be able to log out regardless.
It successfully redirects me to the identity provider login page
That redirect is the key. It opens a browser, where Keycloak cookie is created - that is your IdP session. You have to open Keycloak /logout endpoint in the same browser, so Keycloak can clear own Keycloak cookies.
Summary: you have to open/redirect (API call doesn't work) user to the same browser to the logout endpoint (API call doesn't work) as you have used for the login. Of course this may not be case for some special flows, but it should be working for standard Authorization Code (with/without PKCE).
I am implementing an oauth2 authorization server for providing access to our apis.
Our application is a single page application, with the a jwt token in the authentication header to provide access.
We want to setup an oauth2 Authorization Code flow like,
User is on external site and wants to get access to our apis
External site redirects to our site/spa with oauth2 params, client_id etc.
SPA checks authentication, users needs to login to continue
User sees page for confirming access
User confirms access, code is returned and redirected to external site
External site does backchannel call to obtain token from code
My problem is in 4 and 5, in standard Spring setup this is provided by
org.springframework.security.oauth2.provider.endpoint.AuthorizationEndpoint,
on /oauth/authorize GET oauth params are stored in the session and the confirmation page is shown, and on post of that the code is returned in the redirect.
But I cannot find any guidance/examples on how to do this with a page hosted in a SPA.
You have to be authenticated in this endpoint and I cannot really use the top level page that /oauth/authorized provides because we use header based authentication on rest api calls only, all our top level calls are unauthenticated.
Is there some obvious way to make this work?
I think I do not want to put my authentication token in a cookie.
I was thinking of just then creating a controller that sort of does what the AuthorizationEndpoint does and returning a redirect to the redirect in Javascript. But I am not sure if I would be breaking some other security requirement.
Im having a problem to understand the OAuth flow with Spring.
I have a server running, which got protected endpoints to deliver metric data about the users, revenue usw.
These are used inside an admin panel written in Angular2. Currently the access_token for these endpoints is received by sending the ClientId/Secret and username password to my server.
But obviously its bad to store the Clientsecret on a javascript site.
So I need a way to retreive an access_token from javascript without exposing the client_secret.
I tried to implement the Spring OAuth2 implicit flow which somehow works, but only when I type it inside a browser so the /login page from spring shows up.
My Admin panel has its own Login page so this doesnt work out.
Does anyone have suggestions?
I have a Spring (3.2) based web app that a user can log into. The site will also provide an API secured via OAuth 2.0. My question then, is how do I go about generating a token for a logged in user?
The underlying idea here is that there will be a mobile app that opens up a web frame to the login page, which will eventually redirect to a url schema with an oauth token that the app will catch and then use for the api calls. Looking at the code for TokenEndpoint, I see that it defers token creation to a list of TokenGranter types. Should I be creating my own TokenGranter extended class, or am I looking at this all wrong?
I ended up writing a controller like this:
OAuthClientRequest request = OAuthClientRequest
.authorizationLocation(csOauthAuthorizeUrl)
.setClientId(csClientId)
.setRedirectURI(
UrlLocator.getBaseUrlBuilder().addSubpath(AUTH_CODE_HANDLER_URL).asUnEscapedString())
.setResponseType("code")
.buildQueryMessage();
UrlUtils.temporarilyRedirect(httpResponse, request.getLocationUri());
return null;
Then handling the code returned. My big problem here was that I had the /oauth/authorize endpoint set to use client credentials. Once I realized that tokens were being issued for the client ID instead of the user, it started to make sense.
So you want to use the Authorization Flow of OAuth. Spring has already support that, if you have configured the spring-security-oauth correctly, you just have to redirect the user/your mobile apps to /oauth/authorize?client_id=xxx&response_type=code this will redirect user to authorization page, if user has not login yet, it will redirect the user to login page then to the authorization page.
After the user completed the authorization process, it will redirect the user to an already registered redirect_url parameter with the authorization_code 'yourapp.com/callback?code=xxxx'.
Your application should exchange this authorization_code with the real token access to /oauth/token?grant_type=authorization_code&code=xxxx&client_id=xxxx&client_secret=xxxx
After that you will receive the token access that can be used to access the resource server.
I have implemented an OAuth2 authentication mechanism in my GWT app. The OAuth2 server is based on Spring framework 3.x (using its Spring security OAuth2 implementation).
I am using the OAuth2 "Authorization code flow" to get the user authenticated (though implicit flow may have been a better choice in our case). So at first, the user is redirected to the OAuth2 server authentication page, he enters his credentials and if he is successfully authenticated, he is redirected back to a url with an oauth code. He will then make a second call to get an access token from the OAuth2 server.
Now, the issue is, we would like the user to be able to bookmark a page in the application and directly access it. If he has already authenticated then he would have direct access to it (no more auth involved). Otherwise, he would have to go into the OAuth2 authentication flow but in the end, should be redirected back to the bookmarked page he intended to access at the beginning.
How can I store this page url and get redirected to it after the user successfully authenticates ?
any help would be appreciated. Thanks!
EDITED
The initial url redirection is done via javascript's document.location.href
The way to maintain the original URI in an OAuth 2.0 Authorization Grant flow is to pass it in the state parameter so that the redirection endpoint can use it, after it exchange the authorization code for an access token, to redirect the user back to that URI.
FYI, this is exactly what Google suggests in the examples in their OAuth 2.0 documentation, e.g. https://developers.google.com/accounts/docs/OAuth2Login
Original answer:
The problem is using the hash part of the URL for the place, which is not sent to the server and thus cannot be used in the redirection to the OAuth2 server authentication page.
You have 2 (maybe 3) solutions:
stop using the hash for the place and switch to HTML5 History; either through gwt-pushstate at the History level, or a custom PlaceHistoryHandler.Historian if you use the Places API. That limits your audience though: http://caniuse.com/history
stop using an HTTP redirect, and instead use JavaScript so you can put the hash in the OAuth2 redirect_uri. So instead of redirecting, send an error page with the appropriate scripts bits.
some browsers append the hash to the URL after a redirection, so your OAuth2 server might be able to pick it (in JavaScript) and append it to the redirect_uri. That might depend on the HTTP status code used for redirecting (from experience, it works with a 301, but you don't want a 301 here). Needs testing.
You can do this using GWT activities and places.
