My understanding is that it triggers when there is no user. For example: $ ssh -l "" ssh-server N times (N =3D the number of times to trigger blacklistd), and the SSH serv= er is configured with: KbdInteractiveAuthentication no UseBlacklist yes I would guess a validation, to check if user is not NULL/empty string, etc.= is missing. But I'll let someone more familiar with the code actually address = this issue. Thank you for triaging! --=20 You are receiving this mail because: You are the assignee for the bug.=
