I notice that as part of the PAM/OpenSSH support, the following lines were
added to the pam.conf on -STABLE:

  # OpenSSH with PAM support requires similar modules. The session one is
  # a bit strange, though...
  sshd auth sufficient pam_skey.so
  sshd auth required pam_unix.so try_first_pass
  sshd session required pam_permit.so

For most sets of entries, there's also a kerberos line (witness login):

  # If the user can authenticate with S/Key, that's sufficient; allow clear
  # password. Try kerberos, then try plain unix password.
  login auth sufficient pam_skey.so
  login auth requisite pam_cleartext_pass_ok.so
  #login auth sufficient pam_kerberosIV.so try_first_pass
  login auth required pam_unix.so try_first_pass

Which gets un-commented for Kerberos sites. Could you comment on whether
or not a similar looking line is required for use with KerberosIV and
OpenSSH?
