All of Eicra’s web application has built-in permission system which was based on ACL architecture, so you can set permission for role (group) or given user to separated modules. By using role, you can tune up how a register member can be privileged then normal user how administrator can enjoy more privileged then a registered user and so on.
After having groups, you can create new user for each group. In order to create new user, you go to manage users (User/User in back-end), here you can create, edit, delete or active for any user. User will have default permission according the group that it belong to (thus one user can't belong to many groups). However you can still set special permission for individual user in a group.
You can set permission according as separated. Firstly, unlock the group if it’s locked and click on the “Permission” like to customize / modify a group’s access privileges. Then the following screen will appear to you.
You can now control each and every group’s access privilege just by selecting or deselecting to all module shows up. When you click on the module’s bars above, each module will be expanded and give you option setting up access privilege.
