It is recommended to do at least an online logical backup to a local file before
any complex reconfiguration of the system. A backup of the LDAP database
can be taken in several ways:
1. offline backup of the physical database files
2. offline logical backup of the database files with slapcat
3. online logical backup with ldapsearch

must be stopped first with /usr/sbin/rcldap stop. The physical database
files are located in the directory /var/lib/ldap/. All files there should be

For a logical backup (database dump), run the command
