Andy,
Couple things you do to validate the SET command is working properly prior to trouble-shooting in BI 4.x:
- SETSPN -L <SERVERNAME> [ Provides List of all records against Server ]
- setspn -L <SERVICEACCOUNT>[ Provides List of all records / Servers associated against Service Account ]
- \jdk\bin>kinit <SrvAccount>@FQN <password>
- \winnt\bscLogin.conf [update debug=true ]
These trouble-shooting tip will help you understand if AD Auth is configured properly prior BI 4.x integration. If all works then you know you have BI 4.x related issue.
Good Luck,
Ajay
