Dynamics GP: Insufficient authorization to perform this action

(1) ShareShare
ReportReport
Posted on by

Dynamics GP 2013 installed successfully at Windows Server 2008 R2. Database auto created on SQL Server 2008 R2. Services are created and these are running.

Web service read-write data when it run from Visual Studio  but give an error message when it host on IIS 7.  Error message: "Insufficient authorization to perform this action"

Nothing done for Authentication which is mention on Chapter:8 of "WSInstallAdminGuide.pdf". This part is not clear.

Especially which is mention under "Registering the SPN":

If you have chosen to use Kerberos authentication, you must register the SPN (Service Principal Name) under the following circumstances:

  • Kerberos authentication mode is used.
  • The user under which the Microsoft Dynamics GP Service Host is running is a domain user. You must also include this fully-qualified domain name of this user in the <userPrincipalName> attribute for the configuration file of your web service application.

GP, DB, IIS all are running at different machine.

How and where enable or setup Kerberos authentication mode?
