Single Sign On for Zoho One and .Net application


I am using Okta account for single sign on. I have integrated Zoho One with OKTA using SAML authentication and it works fine. Also I have configured .net web application with okta and the authentication works fine.

My requirement is I have to login to Zoho account and the link in the Zoho should take me to the .net web application without asking me to sign in again.

This is not working for me and I need directions on how to do this.

Please suggest.
