b33edd3956 Bug fix: When the client connects to a server and Kerberos
authentication is  enabled, the  client effectively ignores  any error
from krb5_rd_rep due to a missing branch.

In  theory  this could  result  in  an  ssh  client using  Kerberos  5
authentication accepting  a spoofed  AP-REP.  I doubt  this is  a real
possiblity, however, because  the AP-REP is passed from  the server to
the client via the SSH  encrypted channel.  Any tampering should cause
the decryption or MAC to fail.

e0fbb1d2de Make password attacks based on traffic analysis harder by requiring that
"non-echoed" characters are still echoed back in a null packet, as well
as pad passwords sent to not give hints to the length otherwise.

cb96ab3672 Add code for being compatible with ssh.com's krb5 authentication.
It is done by using the same ssh messages for v4 and v5 authentication
(since the ssh.com does not now anything about v4) and looking at the
contents after unpacking it to see if it is v4 or v5.
Based on code from Björn Grönvall <bg@sics.se>

099584266b Update to OpenSSH 2.3.0 with FreeBSD modifications. OpenSSH 2.3.0
new features description elided in favor of checking out their
website.

Important new FreeBSD-version stuff: PAM support has been worked
in, partially from the "Unix" OpenSSH version, and a lot due to the
work of Eivind Eklend, too.

This requires at least the following in pam.conf:

sshd    auth    sufficient      pam_skey.so
sshd    auth    required        pam_unix.so                     try_first_pass
sshd    session required        pam_permit.so
