in reply to WWW::Mechanize and cisco.com
This url https://sso.cisco.com/autho/forms/CDClogin.html tells me you have money to hire a programmer to write this program for you :)
This url http://developer.cisco.com/web/webex-developer/sso-reference tells me there is probably a better alternative to scraping cdclogin.html
Maybe it involves Net::SAML/Net::SAML2 ... that first URL had a FAQ/Help links, if you have an account, ask about easier ways to automate authentication , they'll probably help you :)
