15.13. Configuring Changelog Encryption

To increase security, Directory Server supports encrypting the changelog. This section explains how to enable this feature.

Prerequisites

The server must have a certificate and key stored in the network security services (NSS) database. Therefor, enable TLS encryption on the server as described in Section 9.4.1, “Enabling TLS in Directory Server”.

Procedure

To enable changelog encryption:
  1. Except for the server on which you want to enable changelog encryption, stop all instances in the replication topology by entering the following command: 
    # dsctl instance_name stop
    Copy to Clipboard Toggle word wrap
  2. On the server where you want to enable changelog encryption:
    1. Export the changelog, for example, to the /tmp/changelog.ldif file: 
      # dsconf -D "cn=Directory Manager" ldap://server.example.com replication dump-changelog -o /tmp/changelog.ldif
      Copy to Clipboard Toggle word wrap
    2. Stop the instance: 
      # dsctl instance_name stop
      Copy to Clipboard Toggle word wrap
    3. Add the following setting to the dn: cn=changelog5,cn=config entry in the /etc/dirsrv/slapd-instance_name/dse.ldif file: 
      nsslapd-encryptionalgorithm: AES
      Copy to Clipboard Toggle word wrap
    4. Start the instance: 
      # dsctl instance_name start
      Copy to Clipboard Toggle word wrap
    5. Import the changelog from the /tmp/changelog.ldif file: 
      # dsconf -D "cn=Directory Manager" ldap://server.example.com replication restore-changelog from-ldif /tmp/changelog.ldif
      Copy to Clipboard Toggle word wrap
  3. Start all instances on the other servers in the replication topology using the following command: 
    # dsctl instance_name start
    Copy to Clipboard Toggle word wrap

Verification

To verify that the changelog is encrypted, run the following steps on the server with the encrypted changelog:
  1. Make a change in the LDAP directory, such as updating an entry.
  2. Stop the instance: 
    # dsctl stop instance_name
    Copy to Clipboard Toggle word wrap
  3. Enter the following command to display parts of the changelog: 
    # dbscan -f /var/lib/dirsrv/slapd-instance_name/changelogdb/replica_name_replGen.db | tail -50
    Copy to Clipboard Toggle word wrap
    If the changelog is encrypted, you see only encrypted data.
  4. Start the instance: 
    # dsctl start instance_name
    Copy to Clipboard Toggle word wrap
