The menu command Edit+Remove permits removing selected user from the list of users, that is, revoke all his permissions to the current GDB.
It is impossible to remove GDB administrator from the list. Besides, the current user cannot remove himself.
The menu command Edit+Remove All allows cleaning the list of users of the current GDB completely. Access control to this GDB is canceled, that means that access for all users becomes free.
The command Edit+Remove All can be performed only by GDB administrator.
The system asks for confirmation before performing the operation of removing users like in any other operations of removing GDB components.
