As a followup to the last message, after looking at the core
dump of aklog, I see that it dumped core during this line:
fprintf(stderr,":\n%s\n", krb_err_txt[status]);
in the midst of this piece of code:
status = krb_get_cred(name, instance, realm_of_cell, &c);
if (status != KSUCCESS) {
status = get_ad_tkt(name, instance, realm_of_cell, 255);
if (status == KSUCCESS)
status = krb_get_cred(name, instance, realm_of_cell, &c);
}
if (status != KSUCCESS) {
fprintf(stderr, "%s: Couldn't get AFS tickets", progname);
fprintf(stderr," for cell %s", cell_to_use);
fprintf(stderr,":\n%s\n", krb_err_txt[status]);
return(AKLOG_KERBEROS);
}
In other words, one of the three kerberos library routines above
returned a bogus error status that turned out to be outside the
bounds of krb_err_txt.
