I have Configured the Authentication of SharePoint 2019 Kerberos and Created a Non-Claims Aware Relying Party Trust on ADFS behind Web Application Proxy with Kerberos Constrained Delegation.
now the sign in page and authentication Works as expected, But the Sign out from the SharePoint web site is not getting completed,
Read some post on the internet and found to use the below PowerShell , but it is not working on the SharePoint 2019 On-Premise
Read Some post related to Sharepoint2010 and SAML Authentication but that does not help
Please suggest how to fix the sign out issue
