The requirements when using HTML FORM based authentication is that the action attribute must be set to j_security_check and the j_username and j_password fields must be used. Specifically,

<form method="POST" action="j_security_check">
<input type ="text" name="j_username">
<input type="password" name="j_password">
</form>

HTTP Form is independent of SSL /HTTPS support, and can be used with or without SSL enabled.
