[keycloak-user] Incorrect redirect_uri in Authorization Code Flow

[Julián D. Zorzenón]

Hi,

I'm trying to setup a public client in Keycloak 6.0.1 to make an
Authorization Code Flow to work but it fails on the post after the redirect.

1. I've create the following client in the realm "test":
client id => keycloak-java-form-example
enabled => on
client protocol => openid-connect
access type => public
standard flow enabled => on
valid redirect uris => http://localhost:9090/*

2. Manually created a user.
3. Created a simple app. When you go to http://localhost:9090/ it redirects
to:

https://keycloak.server:8443/auth/realms/test/protocol/openid-connect/auth?scope=openid&response_type=code&client_id=keycloak-java-form-example&redirect_uri=http%3A%2F%2Flocalhost%3A9090%2Fcb

4. I log in in the form and get the response on the endpoint
http://localhost:9090/cb with a code (for example:
337f8ec8-dbdd-4965-b538-e5a4fbfff6b4.4cb543a8-1585-4bd0-b174-031288cf3032.cf57276c-98a9-48d3-b460-c678af3f8eb2).

5. I make the following POST request:
POST
https://keycloak.server:8443/auth/realms/test/protocol/openid-connect/token
grant_type=authorization_code
client_id=keycloak-java-form-example
code=337f8ec8-dbdd-4965-b538-e5a4fbfff6b4.4cb543a8-1585-4bd0-b174-031288cf3032.cf57276c-98a9-48d3-b460-c678af3f8eb2
redirect_uri=http%3A%2F%2Flocalhost%3A9090%2Fcb

The response is:
400
{"error":"invalid_grant","error_description":"Incorrect redirect_uri"}

I'm not sure what I'm missing.

Thanks
