Rails - Apr 2009 - ssh problem

I create my ssh keys by using Git Bash.exe  and i copy the ssh
file ,and ssh public keys file from my document and past them in
authorized_keys folder in  ssh folder in the config folder

i use deprec and capistrano to depoly my rails application
but when i write  "  cap deprec:ssh:setup_keys    " and  then  give
the ssh public key (ssh.pub)
this message display
                                      "    Could not find ssh public
key(s) for user mahmoud

                                          Please create file
containing ssh public keys in:

                                               config/ssh/
authorized_keys/ssh.pub "

how can i solve this problem?
