Figure 3.8 Proposed Setup for Network Services
CA Management
The purpose of a CA (certificate authority) is to guarantee a trust relationship among
all network services communicating with each other. If you decide that you do not
want to establish a CA, secure server communications with SSL and TLS, but
separately for each individual service. By default, a CA is created and enabled
during the installation. Find details about the creation of a CA with YaST in
Chapter 43, Managing X.509 Certification
information.
LDAP Server
You can run an LDAP service on your host to have a central facility managing a
range of configuration files. Typically, an LDAP server handles user account data,
but with SUSE Linux Enterprise Server it can also be used for mail, DHCP, and
DNS related data. By default, an LDAP server is set up during the installation. If
you decide against the use of an LDAP server, the YaST mail server module will
not work because it depends on LDAP functionality. Nevertheless, you can still
set up a mail server on your system with the help of the Mail Transfer Agent
module. Find details about LDAP and its configuration with YaST in
LDAP—A Directory Service
(page 813) together with some background
(page 681).
