SSL WS2RFC

hello experts

I am trying to define SSL connection on a scenario WS2RFC (sync).

I would like to know if there is a way to avoid the need to use user password in order to enter to the XI, and still have the SSL.

meaning, no need to use user/password in the entrance to the SSL connection, but pass them in the DT, but still, to have the SSL connection?

if this is possible, how can I implement it?

Thanks
