Vim + iTerm2 color issues

I have trouble with the right Vim configuration. I'm using the latest version of Vim as well as the latest version of iTerm2.

I try to get the solarized colorscheme working, but without luck so far.

Here you can see an image with (top left, top right, bottom left, bottom right) iTerm2, Terminal.app, MacVim and my iTerm2 settings.

I also imported the solarized color scheme in iTerm2.

Here the link to my .vimrc
