Greg, we simply can't return a name that ends with a ".", Windows
clients can't cope with that. As you are working on a unix machine you
can do that but samba has to change that before returning it to Windows
clients. Just dropping the dot is not possible it would be way too easy
to have conflicts. Mangling is the only option.

Of course the best thing is for you to make up a policy of not creating
windows-incompatible file names at all.

CIFS works probably just because you are using the unix extensions.
If you disable them you will probably see the same mangled name from
CIFS as well.
