Is there a Golang example of using user and password? Git history suggests there used to be, but it was removed at some point.

We've been using this happily with v.0.6.0, but in v0.7.0 it has no effect and login never occurs (no error). Our previously working code:

func (e *client) ToAdmin(message *quickfix.Message, sessionID quickfix.SessionID) {
	if msgType, err := message.Header.GetString(tag.MsgType); err == nil && msgType == "A" {
		message.Body.SetBool(tag.ResetSeqNumFlag, true)
		message.Body.SetField(tag.Username, quickfix.FIXString(e.username))
		message.Body.SetField(tag.Password, quickfix.FIXString(e.password))
	}
}

Other examples I can find on the 'net (old StackOverflow questions, QF Java docs etc.) suggest this ought to still work, but it would nice to be sure.
