Problem: When attempting to RDP to a Windows machine from the tenant it fails. Credentials have been verified but RDP still does not work.
Cause: The issue is related to this recent Microsoft patch
Currently the Centrify RDP library does not have the patch in the 18.11 release. When attempting to RDP to a windows system that has the patch installed and "Encryption Oracle Remediation" is set to "Force updated clients", then the connection will fail.
Workaround: The workaround is to set the "Encryption Oracle Remediation" to "Mitigated" on the target windows system.
This can be accomplished via Group Policy: Computer Configuration -> Administrative Templates -> System -> Credentials Delegation -> Encryption Oracle RemediationSolution: This will be fixed in a future release.
