Validation problems due to missing form_token_id's on forms

Issue Summary

After digging through the code I found in authcache.js it does a search on all

$("form input[name='form_token_id']").each(function()

So only the forms with a 'form_token_id' will be updated via ajax and therefore pass the validation.

However, fo some reason some of my forms dont have a form_token_id, there is a 'form_token' and 'form_id' but no 'form_token_id'.

You can see yourself at www.bellasearch.co.uk and see the markup for the main search form.

1st question is 'do i need a form_token_id? and if so how do i get it to appear?

If not, then how will this module work without form_token_ids?

Thanks
