have added an Authentication Server in Services | AAA and configured it to use Active Directory.
It successfully connects when tested under Test Authentication Sewrvers Settings.
However, if I edit the AS and enable TLS encryption the test fails with “Failed! Connection timeout” almost immeditaly.
I am confident I have enabled TLS on both of my 2008 servers DCs to at least TLS 1.0.
I have also applied the pertinent MS updates and made the requisite registry changes to allow TLS 1.1 / 1.2; although I am not sure how to test that...?
Any ideas where I need to be looking to resolve this?
