I'm getting older every day, so to make sure I didn't miss something, I
piped above lines through [ sort -u ] and got

        Kerberos 5 version 1.10-beta1
        Kerberos 5 version 1.8.3
        klist returned false
        klist: No credentials cache found (ticket cache FILE:/tmp/krb5cc_1000)

Apart from the different version numbers, there's no difference. In
other words, where's the problem? Both versions of klist appear to
return false.
