Hey guys, I am trying to set up Sophos AD Sync on a new domain controller (Windows Server 2022 Datacenter) and I keep getting the error "The LDAP server is unavailable". This happens regardless of LDAP with SSL or insecure connection on port 389, different user accounts, etc.
I've attached the logs, although I'm not really sure what to make of them. I'm relatively new to all of this so any help would be greatly appreciated!
