Alfresco Explorer NTLM goes blank page

[maf]

I'm configuring NTLM SSO but when I try to get in Alfresco Explorer the page http://alfresco-server:8080/alfresco/faces/jsp/dashboards/container.jsp goes blank.

This is what I can see in the log (only one line)

10:51:08,079 DEBUG [org.alfresco.web.app.servlet.NTLMAuthenticationFilter] New NTLM auth request from 10.10.10.7 (10.10.10.7:31322) SID:41209E276F808DE8200BB7058E2632EA

I get no error or log message only al blank page. Any idea?



The content of alfresco-global.properties authentication section

authentication.chain=alfrescoNtlm1:alfrescoNtlm,ldap1:ldap

ntlm.authentication.sso.enabled=true
ntlm.authentication.mapUnknownUserToGuest=false
alfresco.authentication.allowGuestLogin=false

I have the same problem, Alfresco 3.3.1, active directory, SSO
SSO works from firefox, but in IE I have a blank page

turns out it's because I have apache with mod_jk in front of my alfresco
if I access alfresco directly, no problem
if I use apache and the rewrite rule, I can't do SSO with IE, I get the blank page, firefox has no problem either way
