Server-To-Server Authentication With OrganizationServiceManager?

Apr 7 at 2:40 PM
We have some code a bit like that under "Add Controllers/CrmSdkController" at https://msdn.microsoft.com/en-us/library/mt790171.aspx to get a token, create an OrganizationWebProxyClient, and add the token to the header.

We're wondering if we're able to use this kind of authentication with the PFE OrganizationServiceManager? I thought the constructor that accepts a pre-authenticated instance of AuthenticationCredentials might work, but I'm having trouble figuring out how to do it.
