When working on this, I would appreciate if bug 44645 could also be
resolved. It's a fairly trivial patch.
https://issues.apache.org/bugzilla/show_bug.cgi?id=44645
I also have additional fixes for JNDIRealm that address problems in
connecting to Active Directory. The biggest issue is that during the
authenticate() call, an LDAP search is performed. The current
implementation uses the bind DN/bind password to perform the search or
null credentials (if the bind DN/bind password is not provided).
However, it should also use the credentials being supplied to the
authenticate() call; adding code to do this resolves a giant hurdle in
getting AD authentication to work properly with most Active Directory
setups.
There is also a lifecycle bug in the JNDIRealm that causes
authentication problems if stop() -> start() calls are issued against it.
I was waiting to open bugs and supply patches for these additional
issues until bug 44645 was resolved (since that would give me a new base
for patching). Bug 44645 is a much more severe issue since it affects
all LDAP servers that use invalid or expired SSL certificates. I'll
paste the description I gave in the bug in case anyone sees this message
via search engines:
"This [bug 44645 patch] is necessary so that you can perform customized
SSL negotiation on the connection. For instance, it allows you to
connect to an SSL server with an invalid, expired, self-signed, or
otherwise untrusted certificate. To do this, you just need to write a
javax.net.ssl.SSLSocketFactory that does not perform the normal
certificate validation during the SSL handshake and then specify the
classname on the new setSocketFactory() call added by this patch."

While trying to track down an issue with logins taking a very long time, I
just discovered in the 5.5.26 source code/Javadoc for JNDIRealm (likewise in
the 6.0 documentation) that there's a big bold TODO to support connection
pooling in the JNDIRealm. I think this may be part of the login problem I'm
seeing.
Looking over the current source code, I can see that it's going to require a
fairly extensive refactoring of the JNDIRealm code. I'm willing to take a
shot at fixing it, but wanted to first check with the list on a couple of

Dear Brandon,
re-doing JNDIRealm seems to me very necesary, but for an other
reason as yours, mentioned above.
As I said in my mail (27 Feb 2008 to bug 42579) JNDIRealm is hardly
useable with (Windows Server 2003) Active Directory Domains --
except for very small / trivial cases.
After a long history of frustrations, I solved all the
Tomcat+AD-issues by an own ADweRealms. Experiences are, so far,
100% good (with Apache Tomcat/6.0.16 on JDK1.6.0_05 and before
also with 5.5.x od 1.5.0_y). I offered the solution, already, in
mentioned mail. (got nil reactions)
Perhaps, you could make your newly designed JNDIRealm realy fit for
Active Directory. It would be warmly welcomed by all who tried to
use / would have liked to use (but, as I know from some, gave up)
Tomcat with AD.
Good luck
Albrecht

By the way of JNDI/Tomcat + Active Directory:
JNDIRealm is/was never quite happy with Active
Directory for a variety of reasons. After a bunch
of frustrations (of which the lying isUserInGruop()
was one of the worst), some time ago, I decided to
write a new Realm class, which I may contribute.
http://www.a-weinert.de/java/docs/aWeinertBib/de/a_weinert/realm/ADweRealm.html
ADweRealm searches only one way (performance!) from the
(authenticated) user to his groups. It follows
the quite important group-in-group relations (to
any depth), and so on.
Experiences in a Windows Server 2003 domain (3000+ user
accounts, hundreds of groups etc.) are quite encouraging.
None of the Tomcat + Active Directory problems, which
Google is full of, arised any more.
