According to the documentation multiple listeners are allowed to be configured - 

Trying to configure mdm to listen at more than 1 port results in the following error on the first defined listener with only 1 other working :

HTTP ERROR 500 org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'keycloakSecurityConfigurer': Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.ataccama.server.http.security.keycloak.KeycloakSecurity' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

Am I doing something wrong?
