I am a web developer at Georgetown University, and we regularly set up course sites for professors using the Omeka Classic CMS.
We currently are using the LDAP-Plugin for single sign-on access to our Omeka sites, but the university is moving towards Shibboleth for all single sign-ons.
Are there currently any plugins avaiable for Omeka that would enable this functionality?
Someone talked on the (now-extinct) development list about writing a SAML plugin for authentication some time ago… but I’m not sure they ever released it. At least, I can’t find it.
I’m not certain if those commenters pursued any further development. The largest issues I had implementing CAS was finding a library that did not conflict with the session mechanism Omeka Classic uses, and making sure that the user would be logged out of both Omeka Classic and CAS simultaneously.
