When setting up an Import/Authentication Profile in PPS, which of the following is a required piece of information to connect to an LDAP server?

When configuring a connection to an external directory service like LDAP within the Proofpoint Protection Server (PPS), the most fundamental requirement is the network address of that service. The LDAP server hostname or IP address provides this crucial location information, enabling PPS to establish a network connection. Without this address, PPS cannot communicate with the LDAP server to perform any functions, such as importing user lists or authenticating user credentials. All other configuration parameters, like the Base DN or bind credentials, are secondary to establishing this initial connection.

A. POP3 is a protocol for retrieving email and is unrelated to LDAP directory services configuration.

C. SMTP is the protocol for sending email, not for querying or authenticating against a directory service.

D. IMAP is an email access protocol; its port number is irrelevant for establishing a connection to an LDAP server.

Chapter 4: Users and Groups

Section: "Add an LDAP Profile

" Page 101. The configuration table explicitly lists "LDAP Server(s)" as a required field

stating: "Enter the hostname or IP address of the LDAP server."

2. Proofpoint On-Demand B-S-A-C Administrator's Guide

Chapter 4: Users and Groups

Section: "Configuring an LDAP Profile

" Page 68. This guide for the cloud version shows the same requirement

listing "LDAP Server(s)" as a mandatory field for the server's hostname or IP address.

"Names and Addresses

" explains the fundamental principle that a network service (like LDAP) must have a resolvable name or address for a client (like PPS) to locate and connect to it.
