Since the TYPO3 forum seems a bit dead, I thought I'll try my luck here. If anyone knows a different place to ask, be sure to name it and I'll delete this post.
I recently acquired a project with TYPO3 webistes that I need to migrate from 6.2 to 7.6. I will probably need to rewrite a lot of customized extensions and I want to start with the login system. The main site uses shibboleth_auth (which is discontinued) that has been partially rewritten to fetch login data from different endpoint.
Now, what is the current alternative for this extension? And how do I "extend" an extension so that It can still be upgraded, but also uses my methods? ( in this case, the custom endpoints for login verifications ).
I know that the University of Austria and Munich are currently working on a shibboleth authentication plugin that will work with 7.6. They asked a couple of weeks ago about feature requests and funding.
