tramp (2.1.1-pre); scp asking for password more than once

Subject:	tramp (2.1.1-pre); scp asking for password more than once

--bug report follows this line--

I connect using /scp: method to some linux machine from cygwin, using
latest tramp from CVS and emacs 21.2.

am asked for password and provide it, can list directory contents.

when trying to actually copy a file using "C" in dired showing remote
system, I am prompts again for password.  this seems unnecessary as
password was already provided once.
