Hi all,
So, you are getting an error about the SSPI Context in your addin, and you want to know what to do next.
First check that users are not in a different domain. Cross domain authentication may cause the SSPI context error.
Second, check if the date / time on the SQL Server machine is synchronized with the Domain Controller time. If there is a time difference of more than three or four minutes between the workstation accessing the data warehouse and the SQL Server, you will have problems .
Lastly, follow the instructions on this Microsoft Knowledge Base:
Use Microsoft Kerberos Configuration Manager for SQL Server to fix the issues.
This will require some domain admin rights, so it will have to be executed by the customer's IT dept.
The bulk of this information is available to the customer IT in the Datavision Technical Overview document, version 8 or later, starting on page 28.
