Above, more one important hint about ADFS Proxy.
When you need change the ADFS Proxy Certificate, because you have only one certificate with a lot of names, sometime you will need change the certificate, do the following steps:
Import the new Certificate.
Open PowerShell as Administrator;
Run Get-WebApplicationProxySslCertificate to see the old Certificate
Now, set the new certificate;
Set-WebApplicationProxySslCertificate -Thumbprint “aaxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxab”
Then, restart ADFS Proxy services;
Net stop adfssrv
Net start adfssrv
Run Get-WebApplicationProxySslCertificate to see if the certificate had been changed.
