ArcGIS Online Single Sign-on (SSO) from ArcGIS for Desktop 10.2.2 ?

Hi,

I have a customer who configured Enterprise log-in (SSO) for their ArcGIS Online for Organisation account using SAML. This works fine in browser environment and sign-in page provides option to authenticate using SSO or using explicit username/password.

Now customer wants the same capability in ArcGIS for Desktop 10.2.2 when connecting to ArcGIS Online for Organisation. I cannot see any option to do so. Clicking "My Hosted Services" or Sign-in always asks for username and password. I could not find anything in ArcMap options either. Is it possible to provide ArcGIS Online SSO from ArcMap at all?

Cheers,
Vish
