Slide 2.2 doesnot authorize

Hello all,

I got the Slide 2.2 source code and successfully built and
deployed on Tomcat 5.0.28. However, it doesn't popup the
login dialog for authentication as in Slide 2.1, it always
assumes unauthenticated user. I have replaced the Domain.xml
in Slide 2.2 by the counterpart in Slide 2.1 but got the
same problem. 

Could anyone help me with this issue.

Thank you,
Ha Pham
