Custom Logon Page
I am working on creating custom (new html) logon page for Portal 7.4 than use the standard sap delivered (Fiori Landscape is our user homepage).
I am following this blog to customize.
I am thinking of writing simple html page than use sap logonPage.jsp, Is it right / advisable approach to customize portal logon page?
Where would i able to find Submit Button Action - Validations and Navigation?
