contacts. The user’s contacts are temporarily downloaded to the DSS address book structure and are deleted once the user logs off from the device.

LDAP Replication

On a schedule set by the administrator, DSS connects to LDAP using the specified port, bind method and query parameters. The retrieved information is stored in a hidden, read-only address book which is always available to all devices, similar to the Public Address Book. DSS can search in multiple search roots/contexts, but only from one LDAP server.

Direct LDAP Addressing

The device continues to be able to use its embedded direct LDAP addressing features while serviced by DSS. The device will merge the address book information retrieved directly from LDAP with that retrieved from DSS.

Guest

The Guest address book is always available to all devices and cannot be disabled. This address book is used to store addresses added by un-authenticated users (“guests”) from the front panel of devices.

Personal

The Personal address book feature is automatically activated when users are authenticated at the device. The feature allows users to access and maintain a Personal address book from the front panel of any devices connected to the same DSS server.

An administrator can manage the contents of the Personal address books using the Address Book Management tab in the DSS Configuration Utility.

Direct LDAP Addressing vs LDAP Replication

When a device is serviced by DSS it essentially has two ways of connecting to an LDAP address book. One is using its embedded direct LDAP addressing capabilities, and the other is using LDAP Replication with DSS. This section discusses considerations for when to use one or the other, or both.

Performance

As the primary purpose of the address book features is to provide “auto-complete” functionality it is vital that performance is maintained. For this reason, the HP Digital Sending-enabled devices are designed such that the address book feature for DSS and LDAP respectively are handled in separate threads. Performance is also the reason why for most devices the local address book is not in use when the device is serviced by DSS.

The key parameters that impact performance in terms of addressing for a device serviced by DSS are:

Speed of connection to DSS server

Speed of connection to LDAP server (if used)
