Update grand_master_cas.js

would also need to include 'xmldoc' as dependency. I tried to work around this but unfortunately the default config is to expire tickets as soon as they are used once. Otherwise I would have just reused the ticket to do /serviceValidate. Luckily this path still fits with your intentions. If you accept this then I could keep my dependencies orderly and it would help others I am sure. Otherwise I have already forked this to suit my needs. Have a good day.
