Parent and Child domain LDAP

[Flaxbourne]

Good morning,

I have a question about the LDAP functionality.
Our AD environment has a parent and child domain.

If I configure the LDAP settings I only can add the parent or the child domain to sync but not both at the same time.
Is it possible to configure both?

I did some trial on error things like adding the child domain (ex. ldap://domain.nl,ldap://child.domain.nl or domain.nl,child.domain.nl) but that didn't work out.

Can you configure something like automatic LDAP sync as well?

Thanks in advance.

Kind regards,

Mike
