Figure 3.6 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. Without a CA, you can secure
server communications with SSL and TLS 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
(page 801).
OpenLDAP Server
You can run an LDAP service on your host to have a central facility manage a
range of configuration files. Typically, an LDAP server handles user account data,
but with SUSE Linux Enterprise it can also be used for mail, DHCP, and DNS 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 does not work because
it depends on LDAP functionality. However, 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
(page 661).
If preferred, you can skip this configuration proposal for now. After the installation is
finished, configure and start the same services with the help of YaST.
