Firstly my huge apologies, especially to Toomas Soome, for not replying
earlier on this thread, which I recall he started before Christmas.
I write simply as the person who cobbled together Samba's umtp support,
not with any great knowledge of Samba, nor to defend my less-than-perfect
I seem to recall that the "finger" problem was spotted last summer, but
that the consensus was to live with it as a curious feature.

As I understand (I may be wrong), "utmp*" support requires some sort of
"line". This is what the "/dev/smb/1" invention is: in one sense, simply
a marker. But I also tend to agree with Jeremy et al that Samba probably
should not be diddling with such (pseudo-)devices in the system.
One vital thing to bear in mind, is that utmp* support is incredibly
varied across UNIX systems. The portability considerations are large, as
I discovered the hard way!
Note that I invented "/dev/smb/1" as a subdirectory. This follows the
Solaris model (but note that other systems have a different model: see the
source code). I suppose that, being a self-contained directory, it would
at least constrain any activity, were the decision made to create such
Perhaps there could be yet another parameter: boolean "utmp create line",
propably defaulting off, to allow brave sys.admins to configure their
machines to create these entities. Might that help?
Hope that helps.
