NAME RT::Extension::Captcha - solve a CAPTCHA before some actions in RT DESCRIPTION This extension is for RT 4.2 or newer. It requires solving captchas when a user creates a ticket (using either regular interface or quick create) and on replies/comments (updates). INSTALLATION perl Makefile.PL make make install May need root permissions Edit your /opt/rt5/etc/RT_SiteConfig.pm Add this line: Plugin('RT::Extension::Captcha'); Clear your mason cache rm -rf /opt/rt5/var/mason_data/obj Restart your webserver CONFIGURATION No CAPTCHA rights Users who have right 'NoCaptchaOnCreate' or 'NoCaptchaOnUpdate' will see no captchas on corresponding actions. Font As GD's builtin font is kinda small. A ttf font is used instead. By default font defined by ChartFont option (RT's option to set fonts for charts) is used for CAPTCHA images. As well, you can set font for cpatchas only using "%Captcha option" described below. %Captcha option See etc/Captcha_Config.pm for defaults and example. %Captcha option is a hash. Now, only ImageProperties key has meaning: Set(%Captcha, ImageProperties => { option => value, option => value, ... }, ); ImageProperties are passed into "new" in GD::SecurityImage. Read documentation for the module for full list of options. AUTHOR Best Practical Solutions, LLC BUGS All bugs should be reported via email to L or via the web at L.
