[keycloak-user] Could not find class org.keycloak.adapters.jaas.BearerTokenLoginModule

[Christian Froehlich]

Hello,

I try to use the login module 
"org.keycloak.adapters.jaas.BearerTokenLoginModule" and I just get it 
running when I add the module as “global module” in my standalone.xml. 
What I did to secure my wildfly in detail:
-> Install the keycloak wildfly adapter to my application server
-> Add the login module to my security domain: 
<login-module code="org.keycloak.adapters.jaas.BearerTokenLoginModule" 
flag="sufficient" module="org.keycloak.keycloak-adapter-core">
<module-option name="keycloak-config-file" 
value="${jboss.server.config.dir}/keycloak.json"/>
</login-module>
When I try to login, the login fails and I see the following log in my 
server.log (see below). I also get the error when I remove the module 
attribute from the login-module element. I only get it running when I 
define the “org.keycloak.keycloak-adapter-core” module as a global module. 
Do you have any idea what’s going wrong? I normally expect that the 
LoginModule is found without defining it as global module.
