How to configure SSO for NWBC?

Hi,

I configured the SSO for the SAPGUI with the videos in the link below, but it is not working for NWBC. When I access the NWBC, it is asking me for the login. Which additional steps do I will need to do to complete the SSO for NWBC?

We are using X.509 certificates and the Secure Login Server and SL Client 1.0.

I saw already the documentation in the forum below, but because I have ECC 6 EHP 6 (SAP_BASIS 731 SP14), I do not have the transaction "sncwizard" in my system, so I can't use the process explained in the forum below. That said, is there other way to configure the SSO in NWBC or is this the only way?
