AD Authentication in SAP BOX1 3.1

Hi All,

We have SAP Business Objects X1 3.1 in our environment. We have requirement to enable AD Authentication in SAP.

I have gone through the "SAP Administrator Guide" . We have many domains in our AD based on the region(like EU,LA)

I have created a service account "abc" with the same name in all the domains.

While setting the SPN. Am I supposed to create SPN separately for all the domains(like EU,LA)) with the same service class ?

SETSPN.exe –A <ServiceClass>/<DomainName> <Serviceaccount>

Ex :  SETSPN.exe –A BOBJ/EU abc

        SETSPN.exe –A BOBJ/LA abc

Please help me in this regard

Regards,

Pavithra P
