Microsoft Dynamics GPIf you do a scale-out deployment of the Microsoft Dynamics GP 2013 Web Client you may encounter trust relationship problems if you do not have the SSL certificates correctly installed:

Show/Hide Error Message

An error occurred during session monitoring 'System.ServiceModel.Security.SecurityNegotiationException: Could not establish trust relationship for the SSL/TLS secure channel with authority 'sc1.domain.azurecurve.co.uk:48650'. ---> System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.AuthenticationException: The remote certificate is invalid according to the validation procedure.

In my test environment I was using locally created self-signed SSL certificates. The above error was produced until I exported and imported the certificate from the Session Central onto the Session Hosts and then did the same for the Session Host certificates onto the Session Central.

What should we write about next?
