The second level of security is based on restricting functionality for particular layouts. Every layout has a Layout Security Group assigned to it. Only the functions allowed by the Layout Security Group can be performed on that layout. These functions are identical to the ones that can be assigned to a User Security Group. For example, if the layout security was set to a Layout Security Group that did not allow printing, then any user (regardless of their User Security Group permissions) would not be able to print that layout.
In addition to having security permissions for each action on the layout, a password can be specified for the layout. You will not be able to open the layout without entering the password. The password is stored in an encrypted format. If the password is lost, the only way to open the layout is to send it to De Novo Software.
