I have some forms embedded in a website. Users can only login in to one form. 

Issue I'm having is:

If user enters their correct username and password but on a form they do not have permission to access, they are offered to go to zoho home.

I have created the username and password for them as they are not using zoho, just my site.

How can I ensure that if login fails or login attempted for form that user has no permissions, they do not get the offer of entering zoho profile page.

I would like site to be self contained.

Any help would be appreciated.

Thx,

Rob
