We know that we are able to use OpenID in Meridian Cloud and then redirect to Meridian On-Prem clients. But the we need userpasses and cloud business or portal licenses just for authentication purposes. With Windows 11 it is possible to join PC's directly in the Azure Domain and let users logon to their systems using an email adres (as in Azure AD). But this way SSO will not work because IIS does not support it (Authentication needs to be handled bij the application).
Please enable OpenID authentication on On-Prem servers without the need of Meridian Cloud. With support ending on WIndows 10 this problem is getting bigger and bigger....
