World of Warcraft uses CAS

I had suspected for a while that Blizzard's hugely successful MMORPG, World of Warcraft used JA-SIG/Yale CAS. As a WoW gamer myself, I had noticed the familiar service ticket string in the url when logging into the forums etc.

Well I finally found more confirmation, a Tomcat stack trace is included on this CAS in the wild!, yale blog post.

Talk about scalability.
