NetSuite SSO with Salesforce Identity Provider

I am trying to achieve SAML single sign on between NetSuite ERP and Salesforce.
Here are the steps I followed.

I set up my Salesforce developer account as Identity Provider.

I created NetSuite SAML Configuation

I created a Connected App and entered NetSuite ACS URL.

I created a Salesforce User

I created a Customer record in NetSuite with same Email address and given it SAML custom role.

When Salesforce user clicks on NetSuite URL hyperlink from a Visualforce page, the user is not automatically logged into NetSuite.

What am I doing wrong ?
