This module allows you to manage permissions for content types by role. It
allows you to specifiy custom view, view own, edit, edit own, delete and delete
own permissions for each content type.
Optionally you can enable per content node access settings, so you can
customize the access for each content node.
- it comes with sensible defaults, so you need not configure anything and
everything stays working
- it is as flexible as you want. It can work with per content type settings,
per content node settings as well as with flexible Access Control Lists
(with the help of the ACL module).
- it tries to reuse existing functionality instead of reimplementing it. So
one can install the ACL module and set per user access control settings
per content node.
- it optimizes the written content node grants, so that only the really
necessary grants are written. This is important for the performance of your
- it treats access control as importantly as it should. (e.g. the module has
a bunch of simpletests to ensure that everything is working right.)
- it respects and makes use of Backdrop's built in permissions as far as
possible. This means the access control tab provided by this module takes
these permissions into account and provides you a good overview about the
access control settings that will be applied. 
So the module is simple to use, but can be configured to provide really

Configure a content type under Administration > Structure > Content Types
(admin/structure/types). There will be a new tab called "Access Control".
To make use of
Access Control Lists you'll need to enable per content node
access control settings for a content type. At the access control tab of such a
content node you are able to grant view, edit or delete permission for specific
Running multiple node access modules on a site (Advanced!)
A Backdrop node access module can only grant access to content nodes, but not
deny it. So if you are using multiple node access modules, access will be
granted to a node as soon as one of the module grants access to it.
However you can influence the behaviour by changing the priority of the content
access module as Backdrop applies only the grants with the highest priority.
Content Access has the highest priority alone, only its grants will
By default node access modules use priority 0.

also alter node access. If you have multiple modules installed that alter node
