Java EE (Java Enterprise Edition) General Discussion

Hi now we are working in a Intranet developing of a important company in Spain, we have to integrate this intranet into an Active Directory infrastructure in which users authenticate to.

I'm looking for information about this question, I have found several information about Apache and Tomcat authentication against Kerberos, but I don't know if this works at a real scenario.

This samples are:
Apache sourceforge project about this:
http://modgssapache.sourceforge.net/

Tomcat related : http://www.it-practice.dk/dk/download/53.4852/spnego,kerberos_authentication_with_tomcat.pdf
http://appliedcrypto.com/spnegoarticles.do

Jboss:
http://wiki.jboss.org/wiki/Wiki.jsp?page=NegotiateKerberos

At this moment I only try the Jboss solution but It doesn't work, I have the error log output if you like help me...

What are your opinions ?

Finally I'm so sorry about my English .... and thanks a lot in advance
