Setting database permissions

For the time you install and configure Enterprise Vault, the Vault Service account must be the database owner of all Enterprise Vault databases.

If you changed the database owner after Enterprise Vault was installed, you must make the Vault Service account the owner before you upgrade.

This permission is required to enable database schema and other updates to be enacted with appropriate privileges.

If it is not acceptable to make the Vault Service account the database owner of all Enterprise Vault databases, there is a set of minimum permissions you can apply.
