Hi,
I am working on an ASP.NET MVC site that accesses our local Exchange 2013 server. Everything works fine on my development machine with VS 2013 + IIS Express and the db on SQL Express (on another machine).
The deployed application however throws 401.2 when accessing Exchange with the current user (SQL Server is running on the same server). This should be a problem with Kerberos delegation. Unfortunately I did not get it to work after hours of searching and
configuring. So here's what I have:
- EWS Managed API V2.2
- Windows Authentication enabled in web.config and on IIS
- I use the same domain user when testing on my local machine and the webserver
IIS Configuration:
- Windows Authentication Providers: Negotiate, NTLM
- Windows Authentication Advanced Settings: Extended Protection Off, Kernel-Mode Auth DISABLED
- ASP.Net Impersonation activated on the productive webserver
- Application Pool runs as a domain ...
Go to the complete details ...
