This template is intended to be used as part of the setup instructions for test cases that involve enrolling a system as a domain client. You can invoke it with {{Domain client enrol software|freeipa=0}} or {{Domain client enrol software|freeipa=0}} to leave out the FreeIPA or Active Directory elements when the test case is only relevant to one or the other; otherwise, the instructions will cover both FreeIPA and AD, for test cases that apply to both.
