I am porting from 4.0.3 to 5.0.1 a large EJB 2.0 application that is integrated with a legacy system and includes a custom security module. Some details about what I had to do to get this working initially are described in this post - http://www.jboss.org/index.html?module=bb&op=viewtopic&t=48997 In standardjboss.xml I have added the security-domain element within the jboss element as follows - <security-domain>AproposSecurity</security-domain> In jboss-service.xml for the JaasSecurityManagerService mbean, I have added modified the value of the SecurityManagerClassName attribute for my security module as follows - com.apropos.api.jboss.SecurityRealm This is all the configuration necessary in 4.0.3. JBoss 5.0.1 is not initializing or using my security module. What more must I do to to get 5.0.1 to use my security module?
