Thanks Mike!  Made the change you mentioned, and it works like a charm,
autocreated users with AD info and all.

Last problem, some of our users have the same uid in both domains; this
causes a conflict and a failed login.  Bad planning will always hurt in
the end...

A simple config option is required. It's just not as easy to find as
it's technically a Net::LDAP config option not an ExternalAuth one:

In your RT_SiteConfig.pm:

-   'net_ldap_args'             => [ version => 3 ],
+   'net_ldap_args'             => [ version => 3, port => 3268 ],
