I'm currently giving the sernet.de samba4 (rc1) appliance a shot (running inside vmware player on Windows 7). Providing a share is no problem, but the client still can't choose to encrypt files. What settings do need to be changed in the simplest case? I'm not interested in using AD at the moment, unless necessary.
I'm reasonably certain that Samba4 does not support hosting the Encrypting File System. None of the changelogs since Samba 3.0 mention it as a feature, and the Samba 3 page itself shows it as a feature they'd like to have since Microsoft released details about how it works; which is different than a feature they actually have.
