About Access Rights
You can grant several access rights and combinations of access masks.
- Read
- Read Write
- Add
- Remove
- Add Remove
- Read without Download
If an access right is selected for a particular user, then a set of access masks is granted for that user (see Access Rights and Access Masks Mapping for a list of the masks for each access right). For example, the Read access right grants read, show and checkout access masks to the user. You cannot assign just Read and Show access masks.
If you want a user to be able to read an attached document, but not checkout that document, use the Read without Download access control. This control grants the Read and Show access masks and not the Checkout access mask.
The choice of access control appears in the Add Users pages as well as the Edit Access pages wherever the access right for the user can be selected.
Access Rights and Access Masks Mapping
The access masks associated with access rights are shown in the following table.
| Access Right | Access Masks |
|---|---|
| Read | read, show, checkout |
| Read Write | read, show, checkout, checkin, modify, lock, unlock, revise |
| Add | read, show, checkout, checkin, modify, lock, unlock, revise, fromconnect, toconnect |
| Remove | read, show, checkout, checkin, modify, lock, unlock, revise, fromdisconnect, todisconnect, delete |
| Add Remove | read, show, checkout, checkin, modify, lock, unlock, revise, fromconnect, toconnect, fromdisconnect, todisconnect, delete |
| Read without Download | read, show |
In addition, you can control which access masks are associated with an access control by editing the properties file as described in emxComponents.properties.
