SSO from Enterprise Portal to SAP GUI for Windows

Experts,

I need help in deciding which SSO solution to use.

We are implementing OpenSSO for Single Sign On to Enterprise Portal 7.0. When a user login to his Active Directory account (Windows PC), he is automatically authenticated to EP 7.0 using OpenSSO.

Now, for SSO to SAP GUI (Backend ABAP Stack), I have two options.

1. Launch the SAP GUI for Windows from the Portal to automatically sign into to ABAP using SAP Logon Tickets.

2. Implement SAP GUI for Windows SSO using SNC via Kerberos.

Which method is SAP recommended? What are the advantages and disadvantages of the above two methods, especially option 1?

Saran
