[Samba] encrypting connection to Samba

[Florian Effenberger]

Hello,

I've searched the Howtos, but I did not find anything, so I'm asking
this question onlist.

When are connections between Samba and the client encrypted? I run Samba
3.0.20a on a network with Windows XP SP2 and some Windows 98 machines.

- Are connections always encrypted? Are there any smb.conf settings I
have to make in order to get encryption working (server signing?)?

- Are just authentication requests encrypted or are file transfers
encrypted as well?

Thanks!
Florian
