Thank you for cjoosing to evaluate Sitefinity and for your questions.
When you say 'permissions for content editors' do you mean 'Generic Content permissions'?
I will explain the basics of the Generic Content permissions. They are applied to all generic content items, not for a single item as in pages. So if the user does not have View
permissions, he will not be able to do anything with the Generic Content module. If the user has Create
permission, but he does not have Modify
permission, he can create new content items and then edit only his own items. If the user has Modify
permission, he can also edit other users' items. These permissions are related only to the Administration (Cms users) now.
As for the pages permissions, if you want make a page secure, you can check it's Deny anonymous access
property from the page properties and then set the View
permission for a specific role. Unfortunately, this will not have effect to the site map menu, because it is still not implemented (the task is in our TODO list).
As for your last question, you can set only role-based permissions.
Please let us know if you have a more specific task/question so we could give you a more appropriate answer.
