We’re also using SPNEGO (Kerberos) to do our single sign-on solution here, and 
wanted to jump in to clarify that Kerberos is a protocol and not a type of 
server in this context.  As such, when using this setup, the AD Domain 
Controller speaks Kerberos with the end-user and with the CAS server, but most 
importantly, users don’t need separate accounts to be added to different 
servers for the setup to work.  The hardest part of the setup for a lot of 
folks is just getting the client machines all to be willing to have the 
Kerberos conversation in the first place (if you use IE or Chrome as the 
standard browser this is fairly straightforward for your domain admin; Firefox 
is frankly a pain).
