Hello,

I am trying to setup Web Application Proxy Preauthentication for HTTP Basic application publishing. 

I have Windows 2012R2 std. with Remote Access - We Application Proxy role. 

This Technet article describes how-to publish HTTP basic app: https://technet.microsoft.com/en-US/library/dn765483.aspx

But it when I run Add-WebApplicationProxyApplication command with ADFSforRichClients parameter, it returns an error message:

Add-WebApplicationProxyApplication : Cannot validate argument on parameter 'ExternalPreauthentication'. The argument
"ADFSforRichClients" does not belong to the set "PassThrough,ADFS,ClientCertificate" specified by the ValidateSet
attribute. Supply an argument that is in the set and then try the command again.
At line:1 char:320
+ ... Authentication ADFSforRichClients -ADFSRelyingPartyName 'Exchange EAS'
+                    ~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidData: (:) [Add-WebApplicationProxyApplication], ParameterBindingValidationExcepti
   on
    + FullyQualifiedErrorId : ParameterArgumentValidationError,Add-WebApplicationProxyApplication

It seems that ExternalPreAuthentication parameter on my server only supports "PassThrough,ADFS,ClientCertificate" parameters. But according to technet it should support additional parameters:

-- ADFS
-- ClientCertificate
-- PassThrough
-- ADFSforRichClients
-- ADFSforOAuth
-- ADFSforBrowsersAndOffice

What I am missing?

Thanks on advise.

Martin is right that for Windows Server 2012 R2, you should use these two TechNet links as reference:
 
Publish Applications using AD FS Preauthentication: https://technet.microsoft.com/en-us/library/dn383640.aspx?f=255&MSPPError=-2147217396
Add-WebApplicationProxyApplication: https://technet.microsoft.com/en-us/library/dn283409(v=wps.630).aspx
 
Hope this helps.
