I just wanted to clarify above what the manual states in this section:
How to Adjust SQL Server User Permissions to the required minimum.
This is for the database using mixed authentication.
The user must be part of the administrators group when install is being done and after.
1. VAIM Services
These services should be set to the Windows user.
CA SM Domain Server
CA SM Distribution Server
And keep the rest of the services as they are using system account etc.
With the exception of CA AIP SSH Server which uses sshdUser.
For the created user for the VAIM server Disable UAC Notification, Setup UAC notification to be Never.
3. If you have a message about DPMsystray....
The DPMsystray is just the CA Icon in the taslk bar that can be used to check for new patches etc.
It's not essential but if you wanted to use it then in dos:
cd \program files\ca\virtualassurance\bin
Hope this helps,
