Problem: Unable to access WordPress Admin account and stuck in a redirect login loop after SSO.
Solution: The miniOrange SAML SSO 2.0 plugin uses the WordPress default function: wp_set_auth_cookie() to create the logged-in cookie for the user programmatically.
If WP Engine blocks the wordpress_logged_in cookie creation for a user by a plugin, the user session will not get correctly created on the WordPress site and the user will be stuck in a redirect loop.
In order to resolve the issue, please raise a ticket with the WP Engine support team with the above information so that they can allow our plugin to create the user’s cookie.
