ftp/sftp user account lockout threshold

I've tested it again.

With "deny=2" I can do two failed logons, but if the third attempt is
correct then I log in and the faillog entry is removed.  Which in effect
gives me three logon attempts.

Well, never mind - it does what I want it to do, so everyone's happy.

Thanks very much to Bill for the advise!

No. This means three failed login attempts, and you're locked out. You
don't get a fourth try. I just tested it.
