Connecting CAS 3.1.1 to LDAP

[Zach Seifts]

Hey everyone,

I'm having some trouble trying to setup a cas3 server which connects to 
MS-AD with LDAP (running on etch's tomcat). I've been following the LDAP 
tutorial on the ja-sig wiki and after everything is configured the way 
it says in the tutorial,  I compile and deploy the war file to tomcat 
and it won't start up. The logs tell me i have errors in my 
deployerConfigContext.xml which leads me to think my something in the 
contextSource bean isn't configured correctly. I don't have "ldap://" in 
front of the server name in the urls property, do I need that? Any 
insight would be helpful.

Cheers
Zach
