Access control lists

Mayan EDMS uses a role based permission system (https://en.wikipedia.org/wiki/Role-based_access_control) that provides a mechanism to control access to the contained documents and system functions.

Besides the permissions system explained in the permissions app, Mayan EDMS provides per object permission granting. This feature is used to grant a permission to a role, but this permission can only be executed for a limited number of objects (documents, folders, tags) instead of being effective system-wide.

In this scenario only users in groups belonging to the Accountants role would be able to view the 2015 Payroll report.txt document.

Inherited access control

It is also possible to grant a permission to a role for a specific document type. Under this scheme all users in groups belonging to that role will inherit that permission for all documents of that type.

The role Accountants is given the permission document view for the document type Payroll reports. Now all users in groups belonging to the Accountants role can view all documents of the type Payroll reports without needing to have that permissions granted for each particular Payroll reports type document.

If access control for the Payroll reports documents needs to be updated it only needs to be done for the document type and not for each document of the type Payroll reports.
