Here is a transcript of what I did:

% kinit -l probe
(Entered a lifetime of 1000 minutes -- c.lifetime = 200)

% aklog -cell rel-eng.athena.mit.edu

% saber -lkrb -ldes

#include <des.h>
#include <krb.h>

(struct credentials) =
{
 char service[40] = 0x12a808 "afs";
 char instance[40] = 0x12a830 "rel-eng.athena.mit.e"...;
 char realm[40] = 0x12a858 "ATHENA.MIT.EDU";
 unsigned char session[8] = 0x12a880 /* 0x12a888 */ =
 {
  [0] = (unsigned char) 0xdf,
  [1] = (unsigned char) 0xad,
  [2] = (unsigned char) 0xa7,
  [3] = (unsigned char) 0xe,
  [4] = (unsigned char) 0xa7,
  [5] = (unsigned char) 0x80,
  [6] = (unsigned char) 0x8f,
  [7] = (unsigned char) 0x8,
 };
 int lifetime = -1;

	. . .

Notice that the "lifetime" field of the credentials is -1.  Thus the bug
is in kerberos, not AFS.  The next question is what is in the ktext; I
did not check that out.  I did change all (char lifetime) declarations
in AFS to (unsigned char) in the new AFS 3.0Beta2; there were only a
couple that were incorrect, but those were unrelated to the "tokens"
problem.
