openssh unix dev - Nov 2002 - [Bug 432] New: AIX does not log login attempts for unknown users

http://bugzilla.mindrot.org/show_bug.cgi?id=432

           Summary: AIX does not log login attempts for unknown users
           Product: Portable OpenSSH
           Version: -current
          Platform: PPC
        OS/Version: AIX
            Status: NEW
          Severity: normal
          Priority: P2
         Component: sshd
        AssignedTo: openssh-unix-dev at mindrot.org
        ReportedBy: dtucker at zip.com.au


A login attempt by an unknown user (eg via telnet) normally gets logged as:

syslog: pts/4: failed login attempt for UNKNOWN_USER from my.host.com

This is generated by a call to loginfailed(), which substitutes UNKNOWN_HOST for
the username if it doesn't exist.

AIX never finds out about it because getpwnamallow returns as soon as it finds 
no passwd entry. Following patch calls loginfailed before returning. It 
generates:

syslog: ssh: failed login attempt for UNKNOWN_USER from my.host.com
