This method allows you to add an account in Saner Server. An account requires a unique account name, organization name, email address, start date, expiry date, and number of subscriptions. In case start date and/or end date is not provided, values will default to the administrator’s default values. Please ensure that the start and end date values do not precede or exceed your account's start date or end date values(respectively). The attribute agent auto-upgrade represents that if agents under the account are automatically upgraded, the default value is true. The field organization name must be an existing organization in the Saner server.
