In order to initiate Transport Layer Security you have to call the extended operation ldapSTARTTLS.

I understand that, but this way, even when you're forcing TLS, users can still expose their passwords if their computers are mal-configured. SMTP, IMAP, FTP, etc don't allow this, because they reject the connection if LOGINNAME is given before STARTTLS.
No. RFC 4513 clearly states:
... however, where a client intends to perform both a Bind operation and a StartTLS operation, it SHOULD first perform the StartTLS operation so that the Bind request and response messages are protected by the data security services established by the StartTLS operation. [...]
