Connection zimbra note found

Guys,
I have in my network a samba 4.4.0 with a domain.com as internal domain. This domain has a zimbra that connects to this samba4.

So I migrated all my users to a new internal domain called domain.local and now want those users to connect to zimbra using the UCS user base.

I made the default settings that zimbra requires, but it didn’t work.

Can you help me with that?
