Local service accounts
Prior to Ansible version 2.5,becomeonly worked on Windows with a local or domain
user account. Local service accounts likeSystemorNetworkServicecould not be used asbecome_userin these older versions. This restriction
has been lifted since the 2.5 release of Ansible. The three service accounts
that can be set underbecome_userare:
SystemNetworkServiceLocalService
Because local service accounts do not have passwords, theansible_become_passwordparameter is not required and is ignored if
specified.
