You don't need to purchase a license to use CAS in production :) Some applications that use CAS may require licensing, but CAS itself doesn't (they're licensed under the Apache license - https://www.apereo.org/licensing )
I do know for a fact that TouchNet (a major credit card processor for higher education) uses CAS for its services. (https://secure.touchnet.net/central/ ) You will want to note that all CAS installations don't necessarily have "/cas/" as a part of the URL; you can have the install be simply something like "https://login.org.org/"; Chris -- You are currently subscribed to [email protected] as: [email protected] To unsubscribe, change settings or access archives, see http://www.ja-sig.org/wiki/display/JSG/cas-user
