Hi Brian,

Sorry that my response was aimed at web apps and didn't help. Of course, JAAS originated for the desktop and only became completely integrated into JEE recently. As I mentioned, there's plenty of LDAP code and JAAS tutorials around. If you run into problems, or even as initial research, there is the OpenJDK project at:


I didn't check specifically, but I assume the code for JndiLoginModule is available there. It may be in the standard source download as well. That should give you a running start.

First question is, do you need JAAS? Most app servers allow you to set
the default security mechanism (like LDAP) and you can use form based
authentication, which should also pick up the groups.
If JAAS is necessary, you're probably better off just writing it
yourself with a LoginModule implementation instead of trying to get
something with built-in restrictions (like JndiLoginModule) to work.
There's plenty of LDAP access code around. You can also look at something
like jGuard, but third party add-ons often use additional application
filters. App filters are great, but you can be surprised when and how often
they run.

Thanks for the feedback Joe. I'm looking at using JAAS for Swing apps
(deployed with Web Start). I was initially quite excited to see the
LoginModule implementations in JDK6, in fact it motivated me to migrate
all our Swing code to Java6. I was quite disappointed when I came to
the actual implementation to find these various short comings.

So I guess I'll bite the bullet, and write my own LoginModule. I
suppose at the least I'll learn something from the exercise :P
