We have an ADFS 4 server and a proxy server, and about 10 relying parties set up for various software vendors.
After importing a new relying party metadata file into ADFS, the relying party properties in ADFS show empty Signature and Encryption tabs.
Sign in works fine.
But relying party is not logging out the user after the user clicks log out. It redirects the user to the successfully signed out page, but if a protected page is accessed after signing out, it lets you in as the previously signed in user.
What can be tried to troubleshoot this issue?
