You are correct: the redirect_uri parameter should be pointing back to Special:PluggableAuthLogin. From your example below, it should look something like:
redirect_uri=https%3A%2F%2Fmyserver.org%2Fw%2Findex.php %2FSpecial%3APluggableAuthLogin The redirect_url is computed by the code at [0], which discards all query parameters. As long as you are being redirected to OIDC from https://myserver.org/w/index.php/Special:PluggableAuthLogin, you should be fine. If you are being redirected from https://myserver.org/w/index.php?title=Special:PluggableAuthLogin, however, the title would be stripped off. PluggableAuth is redirected from Special:UserLogin to Special:PluggableAuthLogin by creating the URL at [1] using Title::newFromText( 'Special:PluggableAuthLogin' )->getFullURL() and then being redirected to it. Could getFullURL() be generating the URL in "?title=..." form on your server? Perhaps because of [2]? If so, please let me know. There would have to be a fix to prevent the title query parameter from being stripped.
