Single Sign on with ADFS [For ABAP, Portal and Cloud products]

Hi All,

Requirement :- Configure SSO for ERP ABAP , Enterprise Portal , Fiori [On Premise], SuccessFactors & Ariba [Both are on SAP cloud]

ADFS is getting configured in the company , SAP User ID and AD username is same.

Basically the expectation is , once the user is logged into his/her AD account all other authentication should happen without password.

Can we achieve SSO for all the given SAP products in this scenario? As of now we don't have any plans for buying SSO 3.0

Appreciate your expert advise.
