           Summary: 'groups' command fails on AIX when logged in as root
                    user via SSH.
           Product: Portable OpenSSH
           Version: 4.2p1
          Platform: Other
        OS/Version: AIX
            Status: NEW
          Severity: major
          Priority: P2
         Component: Miscellaneous

The 'groups' command fails on AIX when the user is logged in as root through
SSH. The same does not fail when the root user is logged in via telnet session.
I did not observe this bug on Solaris.

The command 'groups root' gives the correct information. I believe that
'groups' command internally calls 'id -Gn' command. Execution of 'id -Gn' also
fails. 

However, 'su -','su root' and 'su' commands if executed on the AIX machine
after having logged in, the 'groups' command works fine.

Actually, I found this issue while trying to execute a file which failed to
run. The error "User not authorized to perform command" was seen while trying
to execute. The user was not permitted to execute by the file itself. 

I wanted to understand why the permission problem was seen on AIX when logged
in via SSH. Thanks in advance.
