I converted our SharePoint web applications from NTLM to Kerberos the other day. I still haven’t connected to an OLAP cube to test out the conversion, but after changing everything to Kerberos, the web applications are still working. To set up Kerberos the proper way I followed these two blog posts that are very helpful and step-by-step as to how to set it up. Props to Martin for his excellent post and direction on setting up Kerberos Authentication.
