[Bug 516] RhostsAuthentication failing under AIX 4.3.3

           Summary: RhostsAuthentication failing under AIX 4.3.3
           Product: Portable OpenSSH
           Version: 3.5p1
          Platform: PPC
        OS/Version: AIX
            Status: NEW
          Severity: normal
          Priority: P2
         Component: sshd
        AssignedTo: openssh-unix-dev at mindrot.org
        ReportedBy: Alf.Nicolaysen at web.de


It seems to me, that under AIX 4.3.3 ML 10 the Rhostsauthentication fails 
completely. The files .rhosts, .shosts or even .rhosts.equiv and .shosts.equiv 
are completely ignored. 

With my client I ran the following command:

/opt/bin/ssh <hostname> -o RhostsAuthentication=yes -o Protocol=1 -o 
UsePrivilegedPort=yes

And here is the debug output from my server

# /opt/sbin/sshd -f /opt/etc/sshd_config -d -d

The files .rhosts, .shosts and .shosts.equiv are existing with 600 rights on 
AIX. I compiled the version on myself.
