Simple FTP login request rule - just not so simple to me!

Hey all! Anyone have a rule to capture and alert on FTP login requests ONLY?The rules we currently have capture either all FTP's inbound and generate a lot of entries at times, and the standard rules in ftp.rules which to this point have generated none.
A rule I have tried (in several variations) goes something like: alert tcp any any -> $HOME_NET 21 (msg:"FTP Password/Login attempt" \ flow:to_server,established; content:"Password"; nocase;) I fooled around with the wording, added content:"USER"; nocase; and/or added content:"ogin"; nocase;and still not a single hit when I log onto a server. I SEE Password: when I log in manually so obviously something in my logic or my general understanding of rules is lacking. Any wise rule writers out there that can assist would be greatly appreciated!
