You can easily restrict the access of selected pages and navigation nodes to certain groups and users. You just need to create pages.xml and navigation.xml files in folders named after groups and users to which you want to give permission:
sample-ext/portal/group/group-name/your files
sample-ext/portal/user/username/your files
As you know, the permission on a page has two types: access (view the page) and edit.
To configure them, edit the pages.xml file and put tags: <access-permissions> and <edit-permission>.
Currently, eXo Platform supports several access permissions but only one edit permission. It means that you can configure to make many groups to have the access permission but you can only set one group for edit permission.
For example:
<page>
<name>newStaff</name>
<title>New Staff</title>
<access-permissions>manager:/organization/management/executive-board;member:/organization/management/executive-board</access-permissions>
<edit-permission>manager:/organization/management/executive-board</edit-permission>
...
</page>
