Ambassador-->oidc-->Keycloak: Failed to exchange token: oauth2 #17

Closed Romeren closed 4 years ago

Romeren commented 5 years ago

Hello, First a little description of my setup :) In a kubernetes cluster i'm running the following: Ambassador v: 0.72.0 Keycloak v: 5.0.0 and a echo-http-test service serving a "hello world page"

I'm trying to get ambassador-auth-oidc to work as middle-ware between ambassador and keycloak. All services are up and running. Keycloak is configured with realm, client and user. I can navigate to my echo-http-test uri, and it will redirect to keycloaks login page as expected. I login, and i get redirected to ambassador-auth-oidc service "/login/oidc" Here I keep on getting error-code response from ambassador-auth-oidc:

Failed to exchange token.

The full logs of the ambassador service contains:

2019/06/27 15:16:06 Failed to exchange token: oauth2: cannot fetch token: 500 Internal Server Error
Response:

And the logs of from Keycloak say:

Now initially i thought this would be a error on keycloaks side, however i did a bit of a search around stack-overflow and found that the error is caused by a missing redirect_uri parameter in the request between oidc and keycloak.

Hi @Romeren Have you solved this issue ? I have similar issue (see #21 )

Tnx

Romeren commented 4 years ago

I didn't have any hard requirements on using ambassador, so I ended up swapping ambassador out for traefik, which made it work. So i don't have an issue anymore.

So i guess this issue can be closed. 😬

Romeren commented 4 years ago

But i guess that was not quite the answer you were hoping for 😂.... If you find a solution, then i would still be interested to hear about it!

vakrat1 commented 4 years ago

Hi Thanks for getting back to me. I'm waiting for an answer on the issue I've created. I'm really hoping that I get an answer soon, but I don't see too much traffic around the oidc-auth project. My fallback plan is to look for something else, maybe even using Traefik as you did.

As for the Traefik, do you recommend good post/blog that describe how to do it ?

Thanks Yaniv
