You can only work with the users of a library file to which you have full access rights. When you right-click a file of this type in the Library Explorer, you see an Edit option; otherwise, you see a View option.
In a new library file, all users have full access as indicated by the default entry in the Users table. At least one user in the table must have full access before you can downgrade the default Any User rights.
To add a new user
You can add users to a new library file when the file is created, or by right-clicking an existing library file 
Edit.
- In the Library File dialog, click
Users tab
New. The
New User dialog is displayed.
- Enter the new User Name. Depending upon how you want to restrict access, this can be a specific person or a department name.
- Enter a Password and then repeat it in the Confirm Password field. If you do not enter a password, the named user will be able to unlock the library file without typing a password.
- Set the
Access Level for the new user.
We recommend that you add any users that you want to have Full Access, and then downgrade the default Any User to Read Only. For a regime of tighter restrictions, downgrade Any User to No Access, and add Read Only users as required. However, this can prove problematic in practice.
To edit attributes for an existing user
- On the Library File dialog, Users tab, click the user that you want to edit, and then click Edit. The Maintain User dialog is displayed.
- Change the Password and / or set a new
Access Level and click
OK to confirm.
If you do not enter a password the named user will be able to unlock the library file without typing a password.
