missing/bogus user login block after LoginToboggan install?

Hi,
after the install and activation of LoginToboggan, the user login block i had in my left sidebar
has no user login capability any more but instead seems to be gone and replaced with a lone link called "Login/Register"
to the login page ( /user/login?destination=node )

i tried everything i could think of, but to no avail.
how do i get a LoginToboggan-enabled (that is, accepting email or user name) user login block in my left sidebar?
(i expected this module to give the user login block in my sidebar that capability, or did i misunderstand?)
