Log In After ConnectOnly on an FTP Server

Demonstrates the Chilkat Ftp2.LoginAfterConnectOnly method, which authenticates a control connection previously established by ConnectOnly. It takes no arguments, sends USER, PASS, and ACCT when required, then performs normal post-login initialization.

Background: This is the second half of the two-step connect. Beyond sending the credentials, it runs the same post-login setup Connect would — for example issuing TYPE I and any auto-negotiated features — so the session ends up in the same ready state either way. The value of the split is entirely in what you can do in the gap between the two calls.
