So, does that generally mean that if one was fine with the risks involved in using Windows across the LAN, that there would be no additional security exposure to doing the "same thing" with Samba and no LDAP sign/sealing? [Or is it more complicated than that?]

Perhaps related: Are things more secure with Windows clients only? [i.e. Avoiding doing pure LDAP from non Windows clients.]
[I've got some vague notion of how Windows clients handle things - but perhaps I ought to add some more actual knowledge to that vague collection.]

Can someone point me to some good place to start reading to grok the big picture?
