Tomcat NTLM Username lookup in Win7 AD environment - samba or waffle?

I'm writing a Java Tomcat intranet app that uses NTLM to lookup a user's 开发者_JAVA百科name. This is in a Win7 Active Directory environment.

Is it better to use Waffle or Spnego for this? (Or something better?)

Waffle has a huge following now, and will do the job well. But I am bias :)

Turns out the answer was simple LDAP lookups using the Java libraries javax.naming.directory.*.
