Thank you for your great video. Unfortunately, I am facing issues while migrating to Spring Boot 3 with the updated Spring Security. The non-authenticated endpoints are working as expected, but the authenticated endpoints are not working. I am using AbstractLdapAuthenticationProvider, so I would like to know what changes are required. Additionally, I am using custom authentication and authorization filters.

It seems like the way it used to support jsp in springboot 2 has been changed a lot in springboot 3 version. Code won't give any error but the jsp page doesn't showup. Instead it keeps saying too many redirects? Any idea what to be changed on mvc for jsp view?
