I am trying to install vCAC 6.1 and have gotten to the IaaS installation. All of the pre-req items show up as good. I installed SQL 2012 Express to the same server as IaaS. When I get to the "Server and Account Settings" menu in the IaaS configuration I enter in the domain admin account that has sysadmin permissions to the SQL instance and I get the error "Domain user <domain\user> is not valid or database access denied. Validation error 1385." I have tried just about everything I could think of. Windows authentication mode where the user account has sysadmin rights to the instance. I read that the user account may need local admin rights on the server so that has been done. I tried mixed mode and using the sa account, but that yields the same error. I feel like there is some little gotcha that I am missing and I was wondering if anyone may be able to help.
Let me know if more information is needed.
Thanks.
