Hi Ad,
Please take a look at REFDI.chm search for SetSystemPermission.
Seems like we can set it, but the permission lists does not list out the ID for this permission.
Not sure if it is not updated, or they intentionally not disclosing it.
If you ever find what the ID is, please do share it with us.
Note, I believe only a superuser can set this though.
Regards
Edy
