Custom Password Validation on the Dynamics CRM portal.

Hi,

I am working on the Microsoft Dynamics CRM portal.

I want to implement Custom password validation logic on the following pages.

But I couldn't find a page or form to apply custom javascript on. And even though the Microsoft portal is built on the grounds of the ADX but we don't have the source code to edit.

Please help me with this.

Any suggestion is highly appreciated.

Thanks!
