The option Require_Encrypted_Auth only works for explicit SSL, obviously. Since in implicit mode, the SSL negotiation occurs when connecting, whereas explicit only negotiates after "AUTH SSL/TLS". Simply put, there is no way to exclude a user/group/etc. from implicit SSL since all connections must be secure.

You could easily create a second FTP service without implicit SSL and restrict it only to that user.
