This is a small collection of plug in modules for the JavaTM Authentication and Authorization Service (JAAS), which you can find out about here. These modules, in conjunction with JAAS allow Java programs using to perform user authentication against a number of mechanisms including a Windows NT (or 2000) domain. This ability simplifies the creation of NT hosted servlets and JSPs that authenticate users using their familiar OS credentials.
The code is released under the GNU LGPL (Lesser General Public License). It includes a version of Tomas Restrepo's WSSPI library that jumps through all the hoops that the must be jumped through to authenticate a user under Win32. Much credit is due to Tomas; I took a look at the code I was going to have to write to perform this, apparently simple, task and came close to giving up. Tomas' excellent code saved the day. Please don't contact him with questions about this release -- the bits that you're likely to need help with are all my responsibility.
I see two main audiences for this release: those who want to use it as-is and those who are looking for examples of JAAS modules on which to base their own implementations. In either event if you have any comments to make or anything to contribute please get in touch with me, Andy Armstrong.
