Request validation need to be made in the backend

[sharidas]

When user submits the changes to the password_policy app, the validation is required from the server. Say for example in the server we hardly do validation when the check box is checked/unchecked Restrict to these special characters and the text box is empty.

This would also make our server side processing secure. I was thinking of this because this app is closely coupled with guest app + user manangement app.

In case, if my observation is wrong, let me know.
