           Summary: bug in krb4 support for OpenSSH on IRIX 64-bit ABI
           Product: Portable OpenSSH
           Version: 3.6.1p2
          Platform: MIPS
               URL: http://lib.natur.cuni.cz/komanek/webland/html/unix/opens
        OS/Version: IRIX
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Kerberos support
        AssignedTo: openssh-bugs at mindrot.org
        ReportedBy: komanek at natur.cuni.cz

Problem: 'ssh' binary works except krb4 authorization. Issuing

kinit username; ssh -v -1 host

at the end of the debug output one gets following:

debug1: Trying Kerberos v4 authentication.
debug1: Kerberos v4 authentication accepted.
Disconnecting: Kerberos v4 challenge failed!

So the problem is a post-authentication issue on SGI IRIX 6.5.x if OpenSSH is
compiled with 64-bit ABI (both 'cc -64' and 'gcc -mabi=64'). No such problem
appears if any of 32-bit ABIs is used.

Cause: Incorrectly calculated checksum after the Kerberos 4 server response.
