Just coming back from an onsite visit where we had to find and resolve some tricky parts in the whole SSO configuration. I thought some of you might want to configure Kerberos Single-Sign-On between SAP BusinessObjects BI 4.0 and SAP HANA.

What you absolutely need to read and follow:

->General knowledge

Business Intelligence Platform Administrator Guide – http://help.sap.com/bobip40

SAP HANA Administration Guides – http://help.sap.com/hana_platform

->Specific guides

Setting up Single Sign-On (SSO) with SAP HANA and SAP BusinessObjects XI 4.0 – http://scn.sap.com/docs/DOC-36305

1837331 – HOWTO HANA DB SSO Kerberos/ Active Directory

1631734 – Configuring Active Directory Manual Authentication and SSO for BI4  (PDF ATTACHED)

Additional information when you get stuck:

1871302 – No TGS requests were sent from any server attempting to perform SSO to hana via kerberos

The tricky parts or better what helped us:

– Use the latest HANA JDBC driver (comes with HANA Client 1.0 from Service Marketplace) locally and on BI landscape

– Check that the Keytab on all involved machines is NOT generated with KVNO 255 but without and has the same KVNO everywhere

– Enable attribute “Trust this user for delegation to any service (Kerberos only)” on AD for the service users (-> not a requirement from HANA but from BI)

– Make sure you have the correct REALM everywhere, this can be very tricky in a multidomain environment

– Check if you defined the SPN value you get back from the command “setspn -l <AD ACCOUNT>@DOMAIN” in bscLogin.conf and CMC (case sensitive!)

– Test your HANA SSO configuration with hdbsql and GSSChecker.jar (attached to SP note 1813724) from a client machine

– SAP note 1813724 has a Python script attached which verifies your HANA configuration

– SAP note 1476374 provides troubleshooting for BI SSO

Hope this will help you!

Best,
