Body: <p>i understand that you can use the dedupe rule to identify matching record to merge a new record or to create a new record altogether.  Is there a means to reject the new record altogether if a match is not found?  For example, if i use this rule in a profile form submission, it will only allow entries that already has a record in the CIVICRM system due to a match but will reject the entry if no match is found.  Thanks.</p>

Comments.Text: agree with Fabian that an approach that helps identify if the user is already in your system before the form is submitted somehow- what CMS are you using?
