Hello All,

I am new to Key Cloak and trying to integrate this with a very basic two-page application to understand the working and integration basics.

Environment:

1. KeyCloack 1.7.1 Final Standalone

2. A Basic Spring Application deployed on Tomcat 7  

What I have referred:

http://docs.jboss.org/keycloak/docs/1.2.0.Beta1/userguide/html_single/index.html#tomcat-adapter

Tutorial Videos from Youtube Basic 1 and 2

Issues am facing:

When I set auth-method to KEYCLOAK

<login-config>

<auth-method>KEYCLOAK</auth-method>

<realm-name>KnowledgeFlux</realm-name>

</login-config>

I get the following error

Jan 06, 2016 2:12:58 PM org.apache.catalina.startup.ContextConfig authenticatorConfig

SEVERE: Cannot configure an authenticator for method KEYCLOAK

Jan 06, 2016 2:12:58 PM org.apache.catalina.startup.ContextConfig configureStart

SEVERE: Marking this application unavailable due to previous error(s)

When I set auth-method to BASIC

<login-config>

<auth-method>BASIC</auth-method>

<realm-name>KnowledgeFlux</realm-name>

</login-config>

Application runs fine but doesn’t authenticate even though the user is able to login to Keycloak Realm’s account.

What my files look like

Note:  Application’s name is CloakTest and am using the same name for the client and my realm’s name is KnowledgeFlux

I have googled for similar issues with no luck and it’s been a while since I am stuck here.

Please assist.

P.S. Sorry for the essay but I added as much detail as I thought would be necessary.

Thanks,
Pawan
