Wouldn't that hide the ARC checkbox for all managed users?  Also, in case ARC is
disabled by policy, we want to grey out the checkbox (not hide it).

[Polina Bondarenko, 2016/02/12 17:45:00]

Do you mean that if ARC is enabled by policy, then user can use this checkbox? I
thought that if ARC is enabled, it should be enabled without asking user.

[Thiemo Nagel, 2016/02/12 17:53:32]

Yes, sure.  But in that case the checkbox shouldn't be hidden, it should just be
greyed out (and a management icon added to it).  That's what we do whenever a
policy overrides a setting.
