Existing Lead Re-Enquiry on Application Form

Why it matters :

In current application form implementation if an existing lead tries to register again, the student is able to register and proceed further. Now we have an option where the user will be shown a dialog saying you are already existing in the system and asking them to login using credentials sent on email. A new email with Login link and link to reset the password to be sent after showing the popup on the registration page

How it works :

Click and login with the credentials received on registered email ID
