SQL Server Error when tryingt to install the CMS DB on SQL Server 2005 x64

Question

I am trying to install BOEXI R3 on w2k3 64-bit OS in a SQL Server 2005 x64 database, I am currently at the installation step where i Specify an exisiting CMS database. I created a System DSN and tested it, and it was successful. So when I got to the screen where I select my datasource I had to check use trusted connection because the datasource would not show up when Use DSN created by WOW64 option was checked. From there I could select the database I created. Oh yeah, I also made the application server local system account part of my DB admins group so it has full access to the database yet when I click next to connect I get a CMS Database Error: STU000226. here is what I have in my log:

How do I get past this?

Answer 1

The workaround was, I installed the SQL Server Client tools and created a System DataSource  and then had to create a user DataSource  (it is a quirk in the installer I guess) to get past this point in the installation. Now I have an even bigger problem. Everything but the CMS installed and the installer hung at the "Configuring the CMS" part. The installation finished but when I tried to log into the Central managment console I got this error:
Error: Server GSD-RRPT-RDC:6400 not found or server may be down (FWM 01003) null
I looked at the forums for the cause of this error and came to the conclusion that BOEXI does not support an installation on SQL Server 2005 when using Integrated Authentication to the SQL Server. See the engineers here disabled SQL Authentication for the SQL Server and  will not allow it.
Is this true? Or is there a workaround to install the CMS using Integrated Authentication in the DataSource ?
Thanks.
