CAS + Acegi error

[Lopetegui]

Hi,
   I have casified the acegi tutorial sample in order to use CAS. Everything seems to work except one test case described here:
   (I attach a zip with the configuration files (users, acegi security, cas.properties) used and the logs for the aplication , cas server and acces log)
   First my running enviroment
Jboss 4.2.2 with self signed certificate
CAS 3.1.1 properly configured with SimpleTestUsernamePasswordAuthenticationHandler
acegi-security-samples-tutorial-1.0.6 modified to use CAS as authentication, authorizations with inMemoryDAO
IE 6 SP1
Test procedure
1)Start jboss
2)acces acegi sample app with http
3)Redeirected to CAS in https
4)Log a Authenticated user paco but not authorized (see user-cas.properties)
5)accesDenied.jsp page appears but in https
6)back to index.jsp in https
7)change manually in browser to index.jsp page but using http
8)Click link to secure/index.jsp page
9)DNS error page shows in browser !!
Could anybody tell me some indicating about why I am receiving a DNS error page in browser?
thanks in advance.
Regards
