[jboss-user] [Security & JAAS/JBoss] - Accessing Roles from Custom LoginModule return NULL
I have implemented my own login module and configure the login-config.xml file. I am able
to authenticate users. However when I try to access the principal's roles it always
returns null. Tomcat requires the developer to configure different classes for users and
roles and uses the class to differentiate. However in JBoss I have not found the
configuration for this. I am trying to use this LoginModule to secure web servers and
ejb's.
I am guessing that this is my problem.

I tried adding the getRoleSets method as shown below which I got from an example in this
forum, but this did not make any difference.
| public Group[] getRoleSets() throws LoginException {
| Group grp = new JAASGroup("Roles");
| grp.addMember(new JAASRole("friend"));
| grp.addMember(new JAASRole("friends"));
| return new Group[]{grp};
| }
