Hi Stuart,
Actually this was the 16.04 instance. Captcha started to work automagically from yesterday afternoon!
Here is the dump of configuration.db -
/home/httpd/perl/debug/dump_db.pl -u /home/httpd/lonUsers/mathstatdal/configuration.db
scantron = $VAR1 = {
'scantronformat' => ''
};
defaults = $VAR1 = {
'datelocale_def' => '',
'lang_def' => '',
'auth_arg_def' => '',
'auth_def' => undef,
'timezone_def' => '',
'portal_def' => 'http://capa.mathstat.dal.ca'
};
login = $VAR1 = {
'captcha' => 'original',
'coursecatalog' => '0',
'newuser' => '0',
'loginheader' => undef,
'adminmail' => '0',
'showlogo' => {
'logo' => '1',
'img' => '1'
},
'helpdesk' => '1',
'recaptchakeys' => {
'private' => '',
'public' => ''
}
};
I tried the rebuild of gdbm file after renaming the configuration.db file. The result is the same as above.
Users are reporting that everything is working as expected though. Thanks a lot.

Subject: Re: [LON-CAPA-admin] Loncapa Captcha
Hi Balagopal,
When I visited the "Contact Helpdesk" web form on your mathstat server
(reported version: 2.11.2) a few hours ago, a Captcha was included in
the form, and when I submitted with the correct Captcha completed, it
was validated, and the help request was processed. (Perhaps this is
your 14.04 instance?).
Your domain's configuration.db file will be found at:
/home/httpd/lonUsers/mathstatdal/configuration.db
On the filesystem you can view the contents using:
/home/httpd/perl/debug/dump_db.pl -u
/home/httpd/lonUsers/mathstatdal/configuration.db
If necessary you can rebuild the GDBM file from the corresponding
.hist file with the commands:
cd /home/httpd/lonUsers/mathstatdal/
/home/httpd/perl/debug/rebuild_db_from_hist.pl configuration.hist
if you want to test the rebuild first you would use:
/home/httpd/perl/debug/rebuild_db_from_hist.pl -t configuration.hist
However, I would check the backup of your server first, and compare
file size and modification time for the current configuration.db, and
the one in your backup.

Yes it sounds as though the 16.04 version does not have the complete
configuration.db file.
Note: the /cgi-bin/listdomconfig.pl script will output two copies of
the configuration information, each copy beginning with the header line:
Domain configuration for Department of Mathematics and Statistics
(lonmathstat1)
The reason for the duplicates is that the array returned by
¤t_machine_ids() in lonnet.pm will contain
('lonmathstat1','lonmathstat1');
lonnet.pm rev. 1.1351 fixes that; see:
