CakePHP 2.3 and Active Directory/LDAP

CakePHP 2.3 and Active Directory/LDAP

I've been looking for a good authentication tutorial/solution using
CakePHP 2.3 and Active Directory and am coming up dry. Not for want of
trying, I found some good info for Cake 1.3 (took awhile to figure that
out) and I found Analgorithms CakePHP 2.3 idBroker plugin which seems to
be way more than I need but also seems to not work.
Stuff I found:

http://www.analogrithems.com/rant/2012/01/03/cakephp-2-0-ldapauth/
Not much seems to work. I'm relatively new to cake, so I may just be
messing up the install of IdBroker above, as that's the only hit google
comes back with.
I'd just like to get the point where I can debug connecting to my LDAP
source and verifying the authentication. If someone knows of a good
tutorial, awesome, point me to it.
Otherwise I'm stuck trying to figure out the Idbroker plugin that doesn't
seem to work.
