This auxiliary account is assigned the Log on as a service userright and need not have any other user rights. In an Active Directory domain, we recommend using anexisting domain user account instead of the default account.If the machine is part of an Active Directory domain, make sure that the domain's security policies donot prevent the accounts described in this section (whether existing or newly created) from havingthe user rights that were assigned to them.Important: After the installation, do not specify a different user account for the agent service and do not changethe password for the auxiliary account.
