Thanks Josh.
I have tested with Kinit and it was successful. I went through all the settings I'm aware of and made sure the case is all the same.
I'm wondering if I need to use WDeploy? In the Admin guide it states:
The new properties will take effect only after the BOE web application is redeployed on the machine
running the web application server. Use WDeploy to redeploy BOE on the web application server. For
more information on using WDeploy to undeploy web applications, see the SAP BusinessObjects
Business Intelligence Platform Web Application Deployment Guide.
Also, the Microsoft link about seems to be empty?
