S.PNSE: Operation is not supported on this platform on OS X runs.

[StephenBonikowsky]

SUMMARY
Based on Jason’s recent comments we might expect Ntlm and Kerberos to be supported on OS X but it looks like there is still some work to do here.

Failing Tests

• Security.TransportSecurity.Tests#Https_ClientCredentialTypeTests.NtlmAuthentication_RoundTrips_Echo
• Security.TransportSecurity.Tests#Https_ClientCredentialTypeTests.WindowsAuthentication_RoundTrips_Echo
