The server failing the authentication, for some reason. More
information as to why will be in the debug logs from the server.

Whilst OpenSSH 3.9p1 is old (August 2004) - there shouldn't be any
protocol changes between the GSSAPI support in it, and that in the
latest releases.  You don't say what variety (and versions) of
Kerberos you are using on each platform - I assume that FreeBSD is
Heimdal - are your Linux boxes using MIT Kerberos? What encryption
types are you using?

Finding out the error messages from the sshd will go a long why to
pointing the finger of blame!

    Well, here's the output from "sshd -d -d -d -p 2222" on the Linux box:
[...]
debug1: rexec start in 4 out 4 newsock 4 pipe -1 sock 7

To get sensible debug output from an sshd of that vintage you will need
to add "-e" to the command line to force the debug output to stderr.
(That was fixed in more recent versions.)

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
