Integration SSO - OpenLdap

Hi.
I have the following configuration:
SO - Ubuntu 20.04

SSO - Keycloak 14.0.2 Quay.io - Docker

User federation = ldap
Edit Mode = writable
Username LDAP attribute = uid
RND LDAP attribute = uid
UUID LDAP attribute = entryUUID
User Object Classes = inetOrgPerson, organizationalPerson, organizationalUnit
Users DN = dc=example, dc=org

OpenLdap - Osixia - Docker

dc=example, dc=org
ou=groups (objectClass = organizationalUnit)
ou=users (objectClass = organizationalUnit)

When i synchronize from Keycloak it brings me the users that i have in LDAP, but when i create a user in Keycloak, it isn't impact in LDAP Somebody knows how to do it?
