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

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.
