Welcome to the Q&A Forum

Hi Tony, If the "Sign In" form is an element included on the page that you set to rel=canonical, the other instances of the sign in form should be neutralized (in terms of triggering duplicate content errors). Usually, something as small as a sign in form doesn't constitute enough content to trigger the "duplicate" warning. The SE's algo has to account for certain elements that are useful on each page (for example, navigation bars). They are more concerned with people scraping large amounts of written content from other sites or just recycling large portions of their own site for SEO purposes.
