 ticket: 6543
 subject: Reply message ordering bug in ftpd
 tags: pullup
 target_version: 1.7

 user() was replying to the user command and then calling login(),
 which could send a continuation reply if it fails to chdir to the
 user's homedir.  Continuation replies must come before the actual
 reply; the mis-ordering was causing ftp and ftpd to deadlock.  To fix
 the bug, invoke login() before reply() so that the continuation reply
 comes first.
