In case anyone is wondering, I’ve now got a version of rubycas-server
(the sinatra version) running on heroku.
See here - https://github.com/metasoarous/read_only_rubycas_server.
It works a bit differently than the old one, but it does work. In
particular, whereas the old one is both a gem and the actual application
(which not only seemed weird on it’s face but also posed issues with
heroku), this one has been factored out to work as a gem that you
require in your project. So there is some work to do in setting up the
application, but the README on github should get you going without too
If advice, comments, suggestions, critiques, please do let me know.
