Through a University-wide arrangement, we now have the ability to issue InCommon SSL certificates for webservers in the uis.edu domain. There is no cost to obtain these certificates and there is no limit on the number of them we can have.
In the future, as our existing SSL certificates expire, they should normally be replaced with the InCommon certificates. Also, internal servers (like those used for testing and development) that are using self-signed certificates or are not using SSL due to cost concerns can easily use these third-party certificates, making the experience much friendlier for the user.
Let me know if you have any questions.
