I am implementing my first JAAS implementation and have some
problems/questions.
Firstly my commit method of my LoginModule does the following (User and Role
both implement Principal)
// Create a new User Principal with the user name retrieved from the
NameCallback
User user = new User(username);
// Add the principal to the subject
subject.getPrincipals().add(user);
for (int i = 0; i < roles.length; i++) {
// Iterate the role names retrieved from the database lookup
String roleName = roles[i];
// Create a new Role Principal with the role name
Role role = new Role(roleName);
// Add it to the public credentials to see if it works
subject.getPublicCredentials().add(role);
// Add it to the private credentials to see if it works
subject.getPrivateCredentials().add(role);
}
return true;
In the JSP that the application returns to after doing form based
authentication the following occurs
<p>Subject = <%= Subject.getSubject(AccessController.getContext()) %></p>
<p>Remote User = <%= request.getRemoteUser() %></p>
<p>User Prinicipal = <%= request.getUserPrincipal() %></p>
But this produces
Subject = null
Remote User = administrator
User Prinicipal = GenericPrincipal[administrator()]
Why is the subject null please?
The request.isUserInRole() methods for the role names I added to the subject
also return false... has anyone got some helpful ideas please?
If more source is needed I can gladly provide it if will help
