'default_for_enterprise_users' set means that it's mandatory policy for
enterprise users and always configured. Does this patch pass CloudPolicyTest
browser test built for Chrome OS?

[Sergey Poromov, 2016/07/18 10:10:56]

The test passes successfully. I also ran all *Policy* tests.

[Sergey Poromov, 2016/07/18 14:08:34]

No, I was incorrectly building tests. Removed this value here.

Please document that there's an exception for enterprise-managed users.

[Sergey Poromov, 2016/07/18 10:10:56]

I'm not sure which one. That it's false by default for enterprise?

[Thiemo Nagel, 2016/07/22 16:48:13]

Yes, that's what I meant, but you seem to have removed that part in the mean
time.
