ACL means Access Control List it is a more fine-grained method of

granting access to objects. In the case of ACLs, they grant access using
|
|
3 elements: actor, permission, object. In this case the actor is the role,
|
|
the permission is the Mayan permission and the object can be anything:
|
|
a document, a folder, an index, etc. This means = "Grant X permissions
|
|
to role Y for object Z". This model holds the permission, object, actor
|
|
relationship for one access control list.

Fields:

* Role - Custom role that is being granted a permission. Roles are created

in the Setup menu.
