Why does Cyberduck send the FEAT command before USER?
This causes incompatibilities with some FTP servers.
Other FTP clients do log on using USER/PASS before requesting FEAT.
Here are a couple of examples:
On Microsoft FTP server
220 Microsoft FTP Service
FEAT
530 Please login with USER and PASS.
And on Check Point firewall's FTP server:
220 Check Point FireWall-1 Secure FTP server running
FEAT
202 'USER' command expected
(at which point the server terminates the session)
However, FileZilla does accept FEAT before USER:
220-FileZilla Server version 0.9.37 beta

Apologies if this has been mentioned before but couldn't find any when searching trac.cyberduck.ch

We issue a FEAT to determine TLS capabilities of the server. The FTP specification notes that FEAT may be used anytime and we use it to query capabilities to switch to a secure connection. The server can respond with an error message but should not close the control connection.
