I have just set up authentication using SAML for our organization in Zoho. If the custom login URL for Zoho Mail is used to sign in, it automatically redirects to our SAML portal. However, if a user signs in by clicking login on the Zoho website and does not use the custom link, they enter their email, and then it prompts them to enter their Zoho Accounts password instead of redirecting them to the SAML portal. When entering their Zoho password, the user can click more options to sign in with the SAML, but my users are going to be more likely to use their Zoho password.

Is there any way I can have the page automatically redirect to the SSO portal once a user has entered their email address if they're not using the custom link so that users are required to use SSO no matter how they login? It will be easier for users to only have to remember 1 password for the SAML portal.
