RPC over HTTP Authentication and Security

Topic Last Modified: 2005-05-18

The authentication and security benefits of using RPC over HTTP are the following:

* You do not have to allow any Internet ports other than those you already allow for Microsoft® Office Outlook® Web Access, Microsoft Exchange ActiveSync®, or Outlook Mobile Access.
* You must use Secure Sockets Layer (SSL).
* Outlook must send authenticated requests.
* Both the RPC proxy server and the Exchange server authenticate Outlook requests that use RPC over HTTP.
* You do not expose the end point mapper.
* Client computers can access only specified Exchange services on specified Exchange servers.

HTTP Authentication

Internet Information Services (IIS) on the RPC proxy server controls the HTTP session authentication. When you configure the RPC proxy server, you must set the RPC virtual directory to use Basic authentication, NTLM authentication, or both Basic authentication and NTLM authentication. Outlook can send either Basic authentication or NTLM authentication for the HTTP session, depending on how you have configured the Outlook profile. The RPC proxy server Internet Server API (ISAPI) does not accept anonymously authenticated connections.
