I have added debug option and get the message:<br /><br /><em>Challenge-response success!</em><br /><br />But I still can not login as <em>/var/log/auth.log</em> shows:<br /><br /><div class="codetitle"><b>Code:</b></div><div class="codecontent">$su ALICE<br />/var/log/auth.log<br />Jul  7 23:05:01 debian su&#91;11539&#93;: Challenge response failed: No such file or directory <br />Jul  7 23:05:08 debian su&#91;11539&#93;: pam_authenticate: Authentication failure <br />Jul  7 23:05:08 debian su&#91;11539&#93;: FAILED su for ALICE by BOB <br />Jul  7 23:05:08 debian su&#91;11539&#93;: - /dev/pts/5 BOB:ALICE</div><br /><br />Thank you<br /><br />Werner<p>Statistics: Posted by <a href="https://forum.yubico.com/memberlist.php?mode=viewprofile&amp;u=2949">wehe</a> — Tue Jul 08, 2014 6:49 am</p><hr />
