Form validation and business logic

Hi all,

As per my knowledge, Business Logic is the part of Model in MVC architecture.
Please help me with my doubts of form validation, is form validation a part of business logic?
if yes, then why we put this in Controller?
if no, then what is actually a business logic in a authentication module.

Please guys...

Thanks a ton in advance...
