Recent Microsoft security patches may disable the TLS 1.0/1.1 protocol on Windows Servers. If this happens on an ADFS server, the Symantec ADFS plug-in is unable to make a call to the VIP service.
Apply the attached patch to any Windows ADFS server with the VIP plugin installed to enable VIP to use the TLS1.2 protocol.
Applying this patch will reboot the ADFS server automatically. Plan this activity accordingly.
