You can go through the login process by hand in your browser and check (using e.g. Firebug in firefox, Developer Tools in Chrome etc.) what requests are sent to the site when you hit the OK button. Usually this is a POST request with data taken from the login form. Check what data are sent in this request and execute your own post request with:

mechanize.urlopen(URL, POST_DATA). 

You can extract POST_DATA (and post_url) from mechanize's form object using:

form.click_request_data()

but you may need to do some modifications.

Very simple example:

br.select_form(name='form_name')
br.form['login']='login'
br.form['pass']='pass'
post_url, post_data, headers =  br.form.click_request_data()
mechanize.urlopen(post_url, post_data)
