No link to reset Password

After installation, we e don't see a link in the login window.

How can we enable this function?

I've scoured the forum for a solution. But I can not find any solution.

As I found out, should it be a module?

On other installations* I found out, should it be a module? But with this Link i can not open this:

/?module=fileman&page=password_recovery

(*this I found out if I google for other sites in the web)
