I would like to use NTLM authentication with Tomcat so that Iexplorer send automatically both the user id+pwd to webapp. Is this possible?
With \"BASIC\" authent
Yes it is. The Tomcat Wiki references a documentation about Samba code that enables Tomcat to do NTLM authentication.
The Samba community implemented a Servlet filter that allows to athenticate users agains a domain controller.
