Blank screen when accessing the Analyzer

Products

• Information Centric Analytics

Issue/Introduction

When a portal user attempts to create a new view in the Information Centric Analytics (ICA) Analyzer, a blank screen appears. The user has been granted the Can View Analyzer privilege.

Cause

This is caused by a kerberos lookup failure in an environment featuring a three-tiered ICA deployment, with Microsoft Internet Information Services (IIS), Microsoft SQL Server, and Microsoft SQL Server Analysis Services (SSAS) installed on separate servers. An error similar to the following is captured in the Windows System log:

A Kerberos error message was received:

 Error Text: 
 File: <path>\kerbtick.cxx
 Line: 128c
 Error Data is in record data.
