I've used CAS in the past and found it to be excellent for medium sized organisations (<500 employees). It integrates well with Java applications (through Spring Security) and is a very lightweight solution.

An alternative for a much, much bigger approach is OpenSSO developed by Sun. This is a total beast, but meets every conceivable requirement for an SSO policy.
