Alfresco + LDAP failing to open with SSO

Hello,

I'm trying to setup Alfresco 3.3 CE (on Windows XP) in order to connect to a LDAP server (Active Directory) and allow the users to log in using passthru, that is, with the same username and password they have used to log in on Windows, not having to type them again on their browsers. In Firefox I got prompted for username and password, and if I type them I get this on alfresco.log:

10:06:08,036 DEBUG [org.alfresco.web.app.servlet.NTLMAuthenticationFilter] New NTLM auth request from 127.0.0.1 (127.0.0.1:1510) SID:3A91F6953EBF5D7201BD8E07A2B25F55

If I go to about:config and I tweak network.automatic-ntlm-auth-trusted.uris to add it the value http://localhost:8080/alfresco I get an error logging in, the same error that I get using Internet Explorer instead of Firefox:

If I'm not wrong, the only file in which I need to add or modify configurations is alfresco-global.properties. I attach it under these lines. What am I missing?
