[rt-users] integration with LDAP / Active Directory

[Sean Perry]

So I have a shiny new installation of 3.0.3.  We want to use our 
existing user database for most of the obvious reasons.

I have seen the $LookupSenderInExternalDatabase option but I can not 
find any docs that explain how to make it work.  From the contrib dir on 
the ftp site I found some code for LDAP authentication but no help in 
integrating it.

Also, from reading the docs it is not clear to me how users are 
authenticated from the web login.  Does it use the same method as the 
e-mail interface?  Can it?
