Question

Kerberos not working for default SQL instance but it is for the named instance

Asked by: christiegroup

Hi,

I have 2 asp.net 2.0 apps on my IIS server which are configured the same.
The only difference is that the first app connects to a database on the named instance of sql server on our sqlserver box and the second app connects to a database on the default instance of sql server on the same box.

The first app uses kerberos fine but the second app does not. I get an anonymousl ogon error for the second app.
I don't understand why as they both are running on the same IIS server and are both under the default website.

IIf you would like to see information on the setup then see this link as i had problems setting up the kerberos for the first app.
http://www.experts-exchange.com/Software/Server_Software/Web_Servers/Microsoft_IIS/Q_23498979.html

I have also download DelegConfig which shows that kerberos is working.
see here http://www.iis.net/downloads/default.aspx?tabid=34&g=6&i=1434

Any help appreciated.

Thanks

Anthony

What are the SPNs set on the SQL server?

Dave Dietz

 

by: christiegroupPosted on 2008-09-17 at 08:00:34ID: 22499469

Hi Dave,

Thanks for the comment but i have already solved this. I forgot to close it.

I had a duplicate spn. The sqlserver service was originally setup under one domain account but I then changed it it to run under a dedicated domain account. Therefor the service was registered under both accounts.

I will put you down as assisting since no one else reponded.

Thanks

Anthony
