[keycloak-user] How to add gidNumber and uidNumber when federated with openLDAP

Hi Guys, I am trying to find a way to populate the gidNumber and uidNumber when a user is created in LDAP via Keycloak. I don't want to use hardcoded-attribute-mapper as it would put the same value to all the users. Is there is a way to populate these values when a user is created at the Keycloak side? For "posixAccount" in LDAP these are MUST be present attributes and LDAP throws error if these values are not present when a user is created. Eagerly waiting for your reply. Thanks, Shiva
