Paliminary results of testing with MIT krb5-1.3.2-beta2, OpenSSL-0.9.7c
on sun4x_57 with gcc. 

Problem 1:

We are using using Simon's current mods with the "gssapi" method. 
The new code implements the "gssapi-with-mic". I don't see a transition
stratagy to get from using "gssapi" to get to using "gssapi-with-mic",
other then to update all clients and servers at the same time. 
(The SecurtCRT for Windows, does appear to work with either.)

I know we want to get to using only gssapi-with-mic, but need
some time to convert. I would like to see the server offer both
and the client work with both "gssapi-with-mic" and "gssapi" either
 by #ifdef, or a sshd_config flag, or testing the peer's version string.  

I am willing to write this mod if needed. 


Problem 2:

Since kafs.h is not defined in MIT Kerberos, I change the #ifdef
to match the #ifdef used with the code that needed kafs.h.

We have AFS, and call another routine to get the PAG and token.
It does not rely on the AFS libraries, but issues a syscall for
the PAG and fork/exec aklog to get the token. I will be looking 
at how to get this local mod out as well, and use kafs.h and the 
calls you provide.
