Mark, Thierry, thank You. I would really want to execute this command, but the 'config' option is missing in my version 389-ds, so I was asking for advice on how to configure it in another way. Here is the result of the command executing: root@389ldap-test:~# dsconf slapd-instance backend config set --db_lib mdb usage: dsconf instance backend [-h] {list,get,get_dn,create,delete} ... dsconf instance backend: error: invalid choice: 'config' (choose from 'list', 'get', 'get_dn', 'create', 'delete') Version of 389-ds: root@389ldap-test:~# apt show 389-ds Package: 389-ds Version: 1.3.7.10-1ubuntu1 Priority: optional Section: universe/net Source: 389-ds-base Origin: Ubuntu _______________________________________________ 389-users mailing list -- 389-users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to 389-users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/389-users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
