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
