Create user from keycloak in a specific organizational unit


I setuped a Keycloak server using docker and everything’s working fine. I created my realms and added the user federation for all my organizational units. The thing is that when I create a user from Keycloak, it is set in one of my organizational unit but I don’t know how to chose it. I would like to know if it’s possible to select the ldap organizational unit of the user I’m creating.

Thanks for your help,
