Database permissions


We are currently setting up the Enterprise Reporter product with a SQL db on a seperate SQL server. I have prepared a database before starting the installation but it seems I lack permissions to connect to the new database when I try to configure it through the database wizard.

When I check the permissions of the account with which I'm launching the database wizard, I currentl have read/write permissions.
I can't seem to find which exact permissions are required when the database already exists and you just want to connect to it...?

Is there a list of required permissions? Do I need db_owner permissions or... ?


Thanks in advance for your reaction.

Kind Regards,
