Can we use STS to access BW data using BO Enterprise User

Is it possible to access BW data using BO Enterprise User using SSO Connection?

Since SSO is available only for BO SAP user is there any alternative to use SSO for BO Enterprise user?

I Found that STS (Security Token Service) allows SSO. Will STS Support BO Enterprise User to use SSO?

If yes please provide with the settings required to achieve this, on both BW and BO side, and how to use and configer STS?

WE ARE USING SAP BO 4.1 SP2
