Identify and Remove "mod_auth_openidc" Configurations from an AFS-based Virtual Host

Environment

Cosign, AFS

Issue

If your site is currently configured to use OpenID Connect (OIDC) via "mod_auth_openidc" at the web server for authentication, you will need to update your site's application configuration to use OIDC in the application instead. 

Resolution

There are a number of things to look for in your site code/configuration which you will need to review and remove prior to updating to use OIDC .

Look for these things, remove them if you find them:

1. .htaccess file: mod_auth_openidc, mod_authnz_ldap directives

Locate all .htaccess files in your application directories.  Look for all "mod_auth_openidc" related directives and "mod_authnz_ldap" directives and remove those configurations.  For example:

The relevant directives for each of these modules can be found here:

• mod_auth_openidc directives
• mod_authnz_ldap directives
• .htaccess file documentation

2. You will need to configure your site to use OIDC in your application.  This may be application-specific, depending on your application.  Documentation is available for the following applications:
   1. Knowledge Article #8341 Install and Configure OpenID Connect (OIDC) Client for WordPress in an AFS-based Virtual Host
   2. Knowledge Article #8342 Install and Configure OpenID Connect (OIDC) Client for Drupal in an AFS-based Virtual Host
   3. Knowledge Article #8730 Configure a PHP Application to use OpenID Connect (OIDC)

When you are done, contact webmaster@umich.edu and ask us to remove the mod_auth_openidc directives from your websites’ Apache HTTPD server configuration.
