LDAP Authentication and vBulletin 5.05

[roarkh]

I am wondering if someone can point me in the right direction. I am in the process of setting up vBulletin 5.0.5 on our Intranet site. We had started this project with vBulletin 4.x quite a while ago but for various reasons ended up putting the project on hold for a couple of years. At that time I found and installed a module that allowed me to set up authentication through our LDAP server. I need to do the same with vBulletin 5.0.5 but it looks like the module I was using is only supported through version 4. Can someone point me in the right direction for what I need to do to enable LDAP (actually Active Directory) authentication in vBulletin 5.0.5?

Thanks in advance to anyone that can shed some light on this.
