Under Exchange 2010 were several documents and articles giving guidance for Setting up Kerberos for your load balanced CAS-Array. However there is not much in the way of guidance when it comes to Exchange 2013.
I believe that http://technet.microsoft.com/en-us/library/ff808312.aspxand http://blogs.technet.com/b/kpapadak/archive/2011/03/13/setting-up-kerberos-with-a-client-access-server-array.aspx would still be valid.
However I did come across an article http://unifiees.blogspot.com/2012/11/tutoriel-exchange-2013-configurer.html which you have to translate from French. He talks about reconfiguring the user authentication for Outlook Anywhere. Which we did not have to do under Exchange 2010.
Example:
Get-OutlookAnywhere Server-SV-E15-2 -ADPropertiesOnly | Set-OutlookAnywhere -InternalClientAuthenticationMethod Negotiate-IISAuthenticationMethodsNegotiate, Ntlm
I would like to see guidance for 2013 if possible to see if there are any other little areas with the changes in Client Access that the community does not know about yet.
