How to Export an OpenLDAP Database

Backing Up Your OpenLDAP Directory

Learn the process of backing up your OpenLDAP database with this comprehensive tutorial. We'll guide you through exporting your directory to an LDIF file, ensuring your data is secure and restorable. This procedure is designed for CentOS systems with network connectivity and administrative access.

Exporting the Directory

Utilize the slapcat utility to export your LDAP directory efficiently. Follow our step-by-step guide, which starts with running slapcat -b "dc=ldap,dc=example,dc=com" -l backup.ldif. This command will create a backup of your LDAP directory in an LDIF file, which can be used for restoration purposes.

Preparation for Importing

Before importing your directory, it's crucial to stop the LDAP server to ensure data integrity. Execute service stop slapd.service to safely halt the LDAP service. This precaution prevents conflicts during the import process.

Importing the Directory

To restore your directory, use the slapadd utility by running slapadd -f backup.ldif. After importing, change the ownership of data files back to the ldap user with chown -R ldap.ldap /var/lib/ldap/. This step is vital for proper LDAP server operation.

Best Practices for LDAP Database Export

For cloning an OpenLDAP database, slapcat is the recommended tool. It simplifies the export process by generating LDIF files for the entire LDAP tree. For importing these files, ldapadd is the preferred command. It allows importation without shell access to the LDAP server, presenting a more secure method compared to slapadd. Always choose ldapadd or slapadd over ldapsearch and ldapmodify for optimal results.

Frequently Asked Questions

How do I export an OpenLDAP database?

To export an OpenLDAP database, use the slapcat command. Ensure that slapd is stopped before executing slapcat to avoid inconsistencies. For OpenLDAP 2.4 and above, use the -F option with slapcat.

What should I do before importing a database using slapadd?

Before importing a database with slapadd, you must stop slapd and delete the database on the backup server to prevent conflicts and ensure a clean state for the import.

Why am I getting errors when using slapcat or slapadd?

Errors during the use of slapcat or slapadd can occur if slapd is not stopped prior to using these commands or if there are file permission issues. Ensure slapd is stopped and check that file permissions are correctly set.

What does the 'No such object' error mean when exporting the OpenLDAP database?

The 'No such object' error during an export indicates that the target DN of the operation cannot be located. This could be due to typos, unpopulated directories, incorrect file permissions, or other common issues.

How do I prevent common issues when using slapcat and slapadd?

To prevent common issues, follow best practices such as stopping slapd before using slapcat and slapadd, ensuring file permissions are correct, and using the -F option with slapcat in OpenLDAP 2.4+.
