<div>Hi Stuart,</div>
<div><br>
</div>
<div> I checked the capa server again. Please see below -</div>
<div> </div>
<div> libauthen-captcha-perl version - 1.024-1 on 16.04 </div>
<div> </div>
<div> /home/httpd/perl/debug/memcached_dump.pl |grep 'login.captcha'</div>
<div> 'mathstatdal.login.captcha' => 'original',</div>
<div> </div>
<div> But I noticed another issue. As domain co-ordinator on the 14.04 dev vm, listdomconfig.pl </div>
<div> lists info that is several pages long. But on 16.04, the same thing is barely one page long. </div>
<div> I see coursecatagories, cousedefaults etc on 14.04. But on 16.04, all I see is two sections (one is </div>
<div> duplicate of the other) that says defaults, login = $VAR1 and scantron. Could this be corrupted </div>
<div> domain configuration? Could there be a way to regenerate this config. Thanks a lot. </div>
<div> </div>

<div class="PlainText">Hi Balagopal,<br>
<br>
By default, no Captcha is included in the "Contact Helpdesk" web form <br>
(unauthenticated access) linked to from the log-in page.<br>
<br>
A domain coordinator would use: Main Menu > Set domain configuration > <br>
Display ("Log-in page options" checked), then check the "original <br>
(CAPTCHA)" radio button in the "Contact helpdesk" CAPTCHA validation <br>
row and push "Save Changes" to set the public-facing helpdesk to use <br>
Authen::Captcha.<br>
<br>
I tested this on VMs running Ubuntu 16.04 LTS (both 32 and 64 bit) and <br>
found that Captcha was working correctly, with files written to the <br>
captchadb and captchaspool directories when I displayed the helpdesk <br>
web form. When the form was submitted, the Captcha was validated as <br>
expected.<br>
<br>
A plain text display of your domain's configuration is available via:<br>
/cgi-bin/listdomconfig.pl. A domain coordinator can display that URL, <br>
when logged in, with the DC role selected. Look for the captcha item <br>
within the "login = $VAR1 = { }" data structure. You can also check <br>
what has been cached in memcache by running:<br>
<br>
/home/httpd/perl/debug/memcached_dump.pl |grep'login.captcha'<br>
<br>
from the command line.<br>
<br>
On Ubuntu 16.04 LTS:<br>
<br>
sudo dpkg-query -s libauthen-captcha-perl<br>
<br>
reports:<br>
<br>
Version: 1.024-1<br>
Depends: perl, libgd-perl | libgd-gd2-noxpm-perl | libgd-gd2-perl, <br>
libstring-random-perl<br>
<br>
You might check that the libgd-perl and libstring-random-perl packages <br>
are present.<br>
<br>
The version of libauthen-captcha-perl on Ubuntu 14.04 LTS is 1.023-6.<br>
