Single URL Problem. We have a SharePoint 2010 Enterprise environment running on Windows Server 2008 R2 servers. There are (2) application servers with (3) web front ends. Domain/Forest is W2k8 and all users are in the same domain. There is 1 web application, not counting Central Administration. The web application is configured to use CLAIMS authentication and NTLM. The WFE servers are setup to allow CLAIMS authentication. One of the WFE servers is exposed to the internet and it is configured with a custom login/landing page for the extranet zone. Currently the external/public URL is: https://extranet.clientdomain.com. The internal/default URL is https://internal.clientdomain.com. The client would like to use the same URL internally and externally but also require that the landing page with CLAIMS authentication continue to be used for external access with NTLM continuing to be internally w/o CLAIMS or authentication prompting. We have not been able to get this configured for them. We have been able to only do all CLAIMS with the single URL or all NTLM (no landing page) with the single URL but not satisfy both at the same time.
