Can I ask what you mean by work with you closely? I'm not a web developer, but I have a WW 2.19 instance with Shibboleth setup and am happy to provide any information I can that might be of assistance in getting this to work. After applying 2609, in the admin instructors, all the navigation pages are now working, although various actions are still failing (note, have not even tried any of the user course things). Things still broke:
(1) In Accounts Manager, clicking save edit fails, with warning of:
Use of uninitialized value in hash element at template ContentGenerator/Login.html.ep line 12.
Use of uninitialized value in hash element at template ContentGenerator/Login.html.ep line 12.
(2) In Upgrade Courses, clicking Upgrade Courses fails, same error as above
