Allow author to edit the page but not the page properties




   I dont think it is even possible through permissions but still wanted to confirm.  Can we allow users to edit the page so that they can edit the components on the page, but we do not want user to edit the page properties. I tried updating the jcr:modified, jcr:modifiedProeprties, rep:addProperties, rep:alterProperties and rep:removeProperties but  I can could not achieve this requirement. the option to hide/disable fields in page properties is not option as we want some of the super authors group to have that ability. I guess I will have to implement a custom code to check the permissions/groups and then show or hide the fields on the page properties page.

Can someone provide insights if it is possible through the permissions or there is any other way?
