Later, when you create a federation server by using the AD FS Federation Server Configuration Wizard, you must specify this same account on the Service Account wizard page on each federation server in the farm.

This account is necessary for the Kerberos authentication protocol to work in a farm scenario and to allow pass-through authentication on each of the federation servers.

Use this account only for the purposes of the federation server farm. Edit the user account properties, and select the Password never expires check box. This action ensures that this service account's function is not interrupted as a result of domain password change requirements. Using the Network Service account for this dedicated account will result in random failures when access is attempted through Windows Integrated Authentication, as a result of Kerberos tickets not validating from one server to another.

SPNs are used by Kerberos authentication to associate a service instance with a service logon account. This allows a client application to request that the service authenticate an account even if the client does not have the account name. Using network traces such as Wireshark you can determine what SPN the browser is trying to resolve and then using the command line tool, setspn - Qyou can do a lookup on that SPN.
