WAFFLE - Windows Authentication Framework

Build Status Build status Coverity Scan Build Status Coverage Status Maven central Eclipse Dependency Status


WAFFLE is a native Windows Authentication Framework consisting of two C# and Java libraries that perform functions related to Windows authentication, supporting Negotiate, NTLM and Kerberos. Waffle also includes libraries that enable drop-in Windows Single Sign On for popular Java web servers, when running on Windows. While Waffle makes it ridiculously easy to do Windows Authentication in Java, on Windows, Waffle does not work on *nix.

Unlike many other implementations Waffle on Windows does not require any server-side Kerberos keytab setup, it's a drop-in solution. You can see it in action in this slightly blurry video produced for

Jetty support is build using java 7 like everything else. However, using the provided jetty version will require java 8 usage. To continue with java 7, drop back to Jetty version 9.2.13.v20150730.

Legacy 1.7.x Branch

Waffle legacy support. From 1/3/2015 through 1/1/2016 we will continue to support the 1.7.x branch for any bug fixes to legacy items.

Legacy is defined as...

  • Spring 2
  • Tomcat 5
  • Java 6


There're several semi-independent parts to Waffle. Choose the appropriate HowTo.

  • Simple native interfaces in C# and Java to do all things Windows authentication. Useful if you're building a custom client that requires Windows authentication. See Getting Started with WAFFLE API
  • A generic Servlet Negotiate (NTLM and Kerberos) Security Filter that can be used with many web servers, including Tomcat, Jetty and WebSphere. See HowTo.
  • A Tomcat Negotiate (NTLM and Kerberos) Authenticator Valve, built for the Tomcat Web Container. See HowTo.
  • A Tomcat Single Sign-On + Form Authentication Mixed Valve, built for the Tomcat Web Container and allowing users to choose whether to do form authentication (a username and password sent to the server from a form) or Windows SSO (NTLM or Kerberos). See HowTo.
  • A Spring-Security Negotiate (NTLM and Kerberos) Filter. See HowTo.
  • A Spring-Security Windows Authentication Manager. See HowTo.
  • A JAAS Login Module, useful when extending a custom Java client that already implements JAAS to support Windows SSO. See HowTo.

Waffle was created and is sponsored by Application Security Inc.. For a long story, read the Project History. Also, feel free to use this PowerPoint presentation from NYJavaSIG to talk about Waffle.


  • Account lookup locally and in Active Directory via Win32 API with zero configuration.
  • Enumerating Active Directory domains and domain information.
  • Returns computer domain / workgroup join information.
  • Supports logon for local and domain users returning consistent fully qualified names, identity (SIDs), local and domain groups, including nested.
  • Supports all functions required for implementing server-side single-signon with Negotiate and NTLM and various implementations for Java web servers.
  • Supports Windows Identity impersonation.
  • Includes a Windows Installer Merge Module for distribution of C# binaries.
