Splitting bug 34164 up, with this bug referring to the old googleopenidconnect service. At the moment, a successful googleopenidconnect login is sent to opac-user.pl/opac-main.pl or mainpage.pl instead of the page that initiated the login process.
Created attachment 164981 [details] [review] Allow old googleopenidconnect service to redirect to referring page if possible and appropriate.
Can we get a test plan in the commit message with this? https://wiki.koha-community.org/wiki/Commit_messages
