See https://lists.samba.org/archive/samba/2019-July/224346.html second paragraph. Without ssh communication is unencrypted and the server not authenticated.
I haven´t checked details, but I assume password authentication with ldap is even less secure as rsync then likely cannot do challenge/response authentication, implying an attacker can obtain your passwords.
Rsync with ssh public keys managed via ldaps (and trustworthy certificates) is likely a secure option, but I haven´t seen a good tutorial on that. Even if possible however – why not reuse the existing Kerberos authentication and SMB3?
