Login a user programmatically via JAAS

I'm trying to run code within JBoss Container under a different authentication by programatically logging in a user like that (stripped exception handling):

LoginContext ctx = ctx = 
    new LoginContext("MyLoginSchema", 
        new UsernamePasswordCallbackHandler("newuser", "")
    );
ctx.login();

Subject.doAs(ctx.getSubject(), new PrivilegedAction<T>() {
    @Override
    public T run() {
        Subject.getSubject(AccessController.getContext());
        InitialContext ic = new InitialContext();
        EJBContext sctxLookup = (EJBContext) ic.lookup("java:comp/EJBContext");
        Principal principal = sctxLookup.getCallerPrincipal();
    }           
});

Login of newuser works (Call of LoginModule was successful) but Subject.doAs() doesn't associate the new Subject with the EJBContext. The code in the run()-Method still fetches the old user's principal from EJBContext.

I tested another method of retrieving the logged in user but same behavior here:

Subject caller = (Subject) PolicyContext.getContext("javax.security.auth.Subject.container");

Any ideas?

Solution

  • Which LoginModule do you use now? In JBoss 6.1 you had to use ClientLoginModule to authenticate in container.
