A Service Principal Name (SPN) distinguishes a Kerberos-protected service running on an IP host (such as HTTP/foo.bar.com) as a unique entity on a Kerberos-protected network.

A service principal name (SPN) distinguishes a Kerberos-protected service running on an IP host (such as HTTP/foo.bar.com) as a unique entity on a Kerberos-protected network. In the Directory Server, an SPN is used by Kerberos authentication to associate the IP host service instance to a Directory account object. This allows a client application to request that the Kerberized service authenticate an account even if the client does not know the actual account name.
