Changes

In REL1_27 <ref>https://gerrit.wikimedia.org/r/#/c/mediawiki/core/+/243223/58/RELEASE-NOTES-1.27</ref> MediaWiki gained a complete rewrite of it's authentication and authorization system. [https://gerrit.wikimedia.org/r/243223 SessionManager] and [https://gerrit.wikimedia.org/r/195297 AuthManager] classes were introduced to MediaWiki to replace the "there can only be one!" nature of AuthPlugin <ref>https://www.mediawiki.org/wiki/Manual:SessionManager_and_AuthManager</ref>. Thanks to Cindy Cicalese and others, the [[mw:Extension:PluggableAuth|Pluggable Auth]] framework was also completely rewritten to be compatible with the changes introduced. It provides the ability to layer in a variety of authentication systems. For example, RedHat develops the [https://www.freeipa.org/page/Main_Page FreeIPA] system which provides Identity, Policy and Trusts. FreeIPA is an Open Source <ref>note that much of the code is GPL licensed, however since there are multiple components, each has it's own license. See the [https://www.freeipa.org/page/License license page for FreeIPA]. </ref> Identity Management Solution that <ref>quote from the code hosting site (Pagure) for FreeIPA: https://pagure.io/freeipa</ref>

In turn, the FreeIPA wiki website <ref>uses an interesting skin called strapping-mediawiki. Code is hosted at https://github.com/OSAS/strapping-mediawiki as part of the "Open Source And Standards" group. Seems undermaintained with several pull requests and issues. MediaWiki was interested in distributing it back when MAH was release manager.</ref> is integrated with the Fedora Central Login via MediaWiki's Pluggable Auth and OpenID Connect <ref>The Special:Version page of the wiki shows what's installed: https://www.freeipa.org/page/Special:Version</ref>
