heimdal http proxy

[Charles Hedrick]

My use case is a few web applications. Linux user group management, editing our wiki, and responding to help desk tickets. Generic web apps that I would like to use at home. We support CAS, but our university CAS server has disabled SSO. Since I already have a Kerberos ticket to use ssh, it would be nice to be able to get into the web apps without having to do CAS and Duo each time. (My Kerberos tickets also require two factor authentication to get them.)

We use Kerberos and GSSAPI for other things, but not that I’d need at home.
