KerberosRequestorSecurityToken Constructor (String)
Initializes a new instance of the KerberosRequestorSecurityToken class using a service that is associated with the specified service principal name.
Assembly: System.IdentityModel (in System.IdentityModel.dll)
The service principal name must be in one of the following formats: host/<hostname>@<domain> or <hostname>, where hostname is the name of the computer hosting the target Web service and domain is the fully-qualified domain name of the Kerberos realm in which the host computer resides. The service principal name is associated with an account that is running the service and this mapping is stored in the Kerberos Domain Controller (KDC).
