Re: Service Principal Name in Kerberos



Hi Jeffrey,

Well, what is the difference between the case when SPN =
Domain\AppServerUser and when SPN is registered in the form
OurServiceName/host.domain? I don't take into account IE, IIS, etc., because
we don't use them here.

Thanks.

Hi Andrei,

Sorry for the late response. Our MSDN support tool is experiencing some
problem, so I did not see your reply till now.

Regarding this issue, step one is to verify the correct SPN¡¯s are
registered on the appropriate accounts (setspn ¨Cl <account>), step two is
to verify that the server app is configured to use Kerberos and that the
client is choosing it (a network trace might help identify that).

If it is purely a question about whether Kerberos delegation is working,
something like the DelegConfig tool could be useful to test it outside of
the applications. KB842861 is also a good place to start.

Hope this helps.
