Since upgrading to BI 4.2 and Tomcat 8 we observed in Analysis Office (Version 2.2) a Single Sign On problem when would like to connect to BI platform via Windows AD and Kerberos (Vintela). In prior versions SSO worked without any problems.

The error message was the following (error occurs only when opening a workbook via Analysis Office; opening a workbook directly from BI launchpad works as usual):

Logon to BIP-server failed. The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.

To solve this problem you have to add the following command line parameter in the JAVA Options within the tomcat configuration.

-Dorg.apache.catalina.core.ApplicationContext.GET_RESOURCE_REQUIRE_SLASH=true

On Apache Tomcat 8 Configuration Reference you can find addtional information about this parameter.
