[keycloak-user] Validate Implicit token

[Mohan.Radhakrishnan at cognizant.com]

Ok. I was thinking about this procedure.

The adapter verifies the access token. Does it have to contact the verification Rest endpoint ?

Once the token is verified I need the claims for business processing. Does it mean that I have to use the introspection endpont myself ? I don't know how to hit this endpoint because it seems to need the client secret.

So I am trying to verify and also access the claims.

I would use keycloak.js adapter with auth-code flow.  I personally don't like implicit flow for a number of reasons:

* access tokens get stored in browser history

* You have to perform the whole redirect dance when the access token expires

As far as Tomcat goes, we have an adapter for various tomcat versions.  These tomcat instances would probably use bearer tokens to be secured.  So, the javascript app uses keycloak.js to obtain the token.  REST invocations to TOMCAT are secured by a bearer token. Tomcat app has a keycloak adapter installed to be able to verify access tokens.

Hi,
        I have the standalone keycloak server issuing tokens. Client is going to be JavaScript. I enabled ‘implicit’ and issued

http://localhost:8080/auth/realms/MyRealm/protocol/openid-connect/auth?response_type=id_token%20token&redirect_uri=http%3A%2F%2Flocalhost:8000%2F&realm=<redir.aspx?REF=RpMbXbiODMWF_NyemxaXOfH0GSo35bSPEryQzZMvuavFFBqv2LXTCAFodHRwOi8vbG9jYWxob3N0OjgwODAvYXV0aC9yZWFsbXMvTXlSZWFsbS9wcm90b2NvbC9vcGVuaWQtY29ubmVjdC9hdXRoP3Jlc3BvbnNlX3R5cGU9aWRfdG9rZW4lMjB0b2tlbiZyZWRpcmVjdF91cmk9aHR0cCUzQSUyRiUyRmxvY2FsaG9zdDo4MDAwJTJGJnJlYWxtPQ..> MyRealm &client_id= MyRealm &scope=user

I get the id_token. I am used to getting the ‘access token’ in other IDP’s. Are they the same in Keycloak ?

How do I verify the token inside my Tomcat ?
In other installations we run the IDP separately. So I am doing the same with Keycloak.


Thanks,
Mohan
