When installing Desktop Authority for the first time the installer asks as a prerequisite to use two Domain accounts: one account is created as a Domain Administrator (DAAdmin) and the second is created as a Domain User (DAUser).
When configuring the DA Administrative Service for use, the administrator will be prompted for two sets of credentials commonly referred to as service accounts. These two sets of credentials must be members of the Domain Admins group and the Domain Users group, respectively.
These service accounts are used in tandem by the DA Administrative Service to both provision the machine for use with DA and to set the desired configuration settings created in, and published from, the DA management console.
The domain admin account possesses the necessary privileges to run the Administrative Service on a domain controller. As stated previously, the domain admin account also has the ability to administer the machines added to the domain because the Domain Admins group resides in the Local Administrators group of the machine.
