i am using the following code to authenticate user with LDAP...

InitialContext ctx = new InitialContext();
        JaasSecurityManager jsm1 = (JaasSecurityManager) ctx.lookup("java:/jaas/myLoginModule");
        String securityDomain = jsm1.getSecurityDomain();
       
        SecurityAssociationHandler handler = new
        SecurityAssociationHandler();
        Principal user = new SimplePrincipal(j_username);
        handler.setSecurityInfo(user, j_password.toCharArray());
        LoginContext loginContext = new LoginContext(securityDomain,
        (CallbackHandler)handler);
        loginContext.login();
        Subject subject = loginContext.getSubject();

This way it works and is validating the user but when i call this method (request.getUserPricipal() ) is giving me NULL..

Is there any way that i can pass authentication to Servlet like we have in weblogic?

Thanks,

Nick
