All of my deployed OS X devices have the Autofill forms "greyed out". I am pushing restriction profiles to these devices, however, I have the "Allow Safari autofill" option checked. I am unable to resolve this issue, and am looking for help.
When using the Restrictions config profile, I have found that I cannot scope it to machines prior to 10.11 El Capitan, as you see the behavior which you describe above. It works fine on El Cap machines. Try it out to confirm.
