Symptom

The Web Dispatcher is configured for several back-end systems.
By the Active Directory side, dedicated Service Account is using for individual back-end system.

The SPN with web dispatcher host has been assigned to the Service Account belonging to one back-end system.

For example,
SPN: HTTP/<host of web dispatcher> has been assigned to Service Account:SAPServiceABC.(ABC is the system ID).

Is it possible to set the same SPN:HTTP/<host of web dispatcher> individually for each back-end systems?
