Diagnostic tool that helps troubleshoot Kerberos related connectivity issues with SQL Server, SQL Server Reporting Services, and SQL Server Analysis Services

There’s a tool to check Kerberos issue.

Kerberos authentication provides a highly secure method to authenticate client and server entities (security principals) on a network. To use Kerberos authentication with SQL Server, a Service Principal Name (SPN) must be registered with Active Directory, which plays the role of the Key Distribution Center in a Windows domain.
In addition, many customers also enable delegation for multi-tier applications using SQL Server. In such a setup, it may be difficult to troubleshoot the connectivity problems with SQL Server when Kerberos authentication fails.The Kerberos Configuration Manager for SQL Server is a diagnostic tool that helps troubleshoot Kerberos related connectivity issues with SQL Server, SQL Server Reporting Services, and SQL Server Analysis Services. It can perform the following functions:

  • Gather information on OS and Microsoft SQL Server instances installed on a server.
  • Report on all SPN and delegation configurations on the server.
  • Identify potential problems in SPNs and delegations.
  • Fix potential SPN problems.
