How to : Integrating Cisco devices CLI access with Microsoft NPS/RADIUS SK Scratchpad

I configured NPS 2013 server properly and I have done it several times ago for client authentication using laptops or desktops. This time I am trying to access from Qlogic 8gb 20 port SAN switch module for IBM blade center but, username or password is not diagnosed from the switch. Switch is continually configured and pointing to Radius server that is windows 2012 NPS server. How can I troubleshoot this so I can log in from switch as radius client.

Default switch account works without a issue but, Active Directory account has issue. We use LDAP authentication for AD users. All setup is verified and is accurate.
