I’ve been struggling with kerberos authentication and SharePoint (in combination with SSAS and SSRS Server) for quite some days now. I found something useful in creating the SPN’s needed for kerberos. It’s an Excel sheet, in which you enter some values of your environment and he will return you the SETSPN’s you need to do.

You can download it here: Excel Sheet SPN Calculator.

Special thanks goes out to user SPRobot of the site www.sharepointblogs.com, who posted the sheet.
