This plugin is for a very specific use case: Your WordPress website is part of an organization that uses OpenID Connect (OIDC) for web single-sign-on as well as for group-based authorization. In that case, this plugin will let you restrict access to parts of your WordPress website based on OIDC login and group membership information.
This plugin has been tested with:
<ul>
<li><a href="https://www.shibboleth.net/" rel="nofollow ugc">Shibboleth</a> OIDC using the <code>edumember_ismemberof</code> attribute for LDAP group membership.</li>
</ul>
Features:
<ul>
<li>Allow site visitors to log in via OIDC without needing a WordPress user account.</li>
<li>Optionally allow WordPress users to log in via OIDC instead of using their WordPress password.</li>
<li>Optionally restrict access to the entire site to logged-in users or only members of specific groups.</li>
<li>Optionally restrict access to specific pages and posts to logged-in users or only members of specific groups.</li>
<li>Show parts of pages/posts/widgets only to logged-in users or members of specific groups.</li>
<li>Access restrictions apply to site visitors, feeds, the REST API, and XMLRPC.</li>
<li>Shortcodes (Gutenberg blocks planned for a future release)
<ul>
<li><code>umich_oidc_button</code> – Generate a login or logout button.</li>
<li><code>umich_oidc_link</code> – Generate a login or logout link.</li>
<li><code>umich_oidc_logged_in</code> – Show content only if the visitor is logged in.</li>
<li><code>umich_oidc_member</code> – Show content only if the visitor is a member of one or more groups.</li>
<li><code>umich_oidc_not_logged_in</code> – Show content only if the visitor is NOT logged in.</li>
<li><code>umich_oidc_not_member</code> – Show content only if the visitor NOT a member of the specified groups.</li>
<li><code>umich_oidc_url</code> – Generate a login or logout URL.</li>
<li><code>umich_oidc_userinfo</code> – Display information about the currently-logged-in OIDC user.</li>
</ul>
</li>
</ul>
<h3>Restricting private content in search results</h3>
You can prevent content from showing up in web search engine results by restricting access to particular pages/posts.
Search results from WordPress’ built-in search will only show content that the searching user has access to.
WARNING: WordPress search plugins may show content that the user does not have access to, leaking private information. Please test search plugins before enabling them. If a search plugin provides an appropriate WordPress hook for limiting search results, contact us, and we may be able to add support for it to UMich OIDC Login.
