I did something different:

In the users_controllers.rb

  def edit
    @user = User.find(params[:id])
    params[:action] = :edit
  end

  def update
    @user = User.find(params[:id])    
    if @user.authenticate(params[:user][:current_password])    
      params[:user].delete :current_password      
      respond_to do |format|      
        if @user.update_attributes(params[:user])
          format.html { redirect_to users_url, notice: "User #{@user.name} was successfully updated." }
          format.json { head :ok }
        else
          format.html { render action: "edit" }
          format.json { render json: @user.errors, status: :unprocessable_entity }
        end
      end      
    else
      redirect_to edit_user_path(@user), notice: 'Current password is incorrect'
    end      
  end

in the _form.html.erb (users)
I added:

      <% if params[:action] == :edit %>
        <div>
          <%= f.label :current_password, 'Current password' %>
          <%= f.password_field :current_password, size: 40 %>
        </div>
      <% end %>    

in the edit.html.erb (users)
I added:

<% if notice %>
  <p id="notice"><%= notice %></p>
<% end %>  

<strong>
Following line doesn't display correctly in browser:<br />
<p>if @user.authenticate(params[:user][:current_password])</p><br />
Instead it should looks like this:<br />
<p>if @user.authenticate(params&#91;:user][:current_password])</p>
