Service Principal

Specifies the Kerberos principal that is used for authentication. Use the following format:

HTTP/hostname.domainname@dc-domain-name

hostname and domainname represent the host name and domain name of the Federation Manager instance. dc-domain-name is the Kerberos domain in which the Windows 2000 Kerberos server (domain controller) resides. It is possibly different from the domain name of Federation Manager.
