In this demo, we are using self-signed certificates. It is also known as TLS upgrade operation. STARTTLS: STARTTLS connections begin as a plaintext over the standard LDAP port (389), and that connection is then upgraded to SSL/TLS.LDAPS: LDAPS communication usually occurs over a special port, commonly 636.LDAP supports two methods to encrypt communications using SSL/TLS: Restart log rotation service systemctl restart logrotate Configure LDAP with SSL/TLS Certificates You can as well configure log rotation vim /etc/logrotate.d/slapd /var/log/slapd.log You should now be able to read the LDAP logs on, /var/log/slapd.log. Restart Rsyslog and SLAPD service systemctl restart rsyslog slapd By default, OpenLDAP logs to local4 facility, hence, to configure it to log to /var/log/slapd.log for example, execute the command below echo "local4.* /var/log/slapd.log" > /etc/rsyslog.d/nf Next, you need to specify the log file for OpenLDAP on Rsyslog configuration. To confirm the changes ldapsearch -Y EXTERNAL -H ldapi:/// -b cn=config "(objectClass=olcGlobal)" olcLogLevel -LLL -Q dn: cn=config ![]() You can as well use LDIF files to update this information if you like. Once you see a line, modifying entry "cn=config", then press Ctrl+d. The paste the content below to modify the log level. If you need to change this to a different log level, say to stats level (logs connections/operations/results), run the command below ldapmodify -Y EXTERNAL -H ldapi:/// -Q ldapsearch -H ldapi:/// -Y EXTERNAL -b "cn=config" -LLL -Q | grep olcLogLevel: olcLogLevel: none By default, OpenLDAP logging level is set to none which is required to have high priority messages only logged. Log files is the first place you might want to be checking in case something is not working out. To view the RootDN, run the command below ldapsearch -H ldapi:/// -Y EXTERNAL -b "cn=config" -LLL -Q | grep olcRootDN: olcRootDN: cn=admin,dc=kifarunix-demo,dc=com Configure OpenLDAP Logging on Ubuntu 20.04 ldapsearch -x -LLL -b "" -s base namingContexts dn: In our example setup, the base DN is set to dc=kifarunix-demo,dc=com, root DN is set to cn=admin,dc=kifarunix-demo,dc=com. Choose to remove SLAPD database when slapd package is removed.Re-enter the name of your administration password and confirm it. ![]()
