Multisite – Return to subdirectory based sub-site

Hello:

I am running a sub-directory based WP-Multisite with approx 300+ sub-sites. We are attempting to use the plugin with our Google SSO SAML login.

Would I require a separate .pem file in my root directory for each site I want to lock down with SAML, or would a .pem file from Google SSO have to contain information about the sites that need to be locked down?

Right now we have it working in the root directory, but if I activate the plugin in a sub-directory based subsite such as https://website.com/subdirectoy-site/ I get an error “Error: app_not_configured_for_user“.

Thanks for reading.
