Set to True to run the job under the Local System account or False to use a user account (UserID and Password must be supplied). 

By default, the option to use the Local System account does not appear in the adTempus Console user interface, and Arcana Development strongly discourages you from using the Local System account. 

See Arcana Development knowledge base article K00000036 for information on enabling the Local System options in the adTempus Console, and for cautions and limitations related to the Local System account. 

If UseLocalSystemAccount is True, the caller must have the saUseSystemAccount right for the server (set using the ServerSecurityDescriptor) or the job's Save method will fail and validation will return error ADT_E_SYSTEM_ACCOUNT_NOT_ALLOWED.
