How to reset user password from the admin interface

Question

In my website, I want to let the admins reset the password of any user.

With reset I mean exactly what the password_reset view does (under contrib.auth): Send a confirmation link to that user email.

How would be the best way of doing that? Is there an already app/snippet that does that?

Edit:

Let's suppose user john is an admin. What I want is to let john reset any user's password through the admin interface. For example, to reset max password, he will just go to the max user, and click on any link to reset his password.

What I finally did was to add a custom ModelAdmin:

from django.contrib.auth.forms import PasswordResetForm
from django.contrib.auth.admin import UserAdmin


class CustomUserAdmin(UserAdmin):
    ...
    def reset_password(self, request, user_id):
        if not self.has_change_permission(request):
            raise PermissionDenied
        user = get_object_or_404(self.model, pk=user_id)

        form = PasswordResetForm(data={'email': user.email})
        form.is_valid()

        form.save(email_template_name='my_template.html')
        return HttpResponseRedirect('..')

    def get_urls(self):
        urls = super(UserAdmin, self).get_urls()

        my_urls = patterns('',
            (r'^(\d+)/reset-password/$',
                     self.admin_site.admin_view(self.reset_password)
            ),
        )
        return my_urls + urls

and I also had to override the change_form.html template, like this:

{% extends "admin/change_form.html" %}
{% load i18n %}
{% block object-tools %}
    {% if change %}{% if not is_popup %}
        <ul class="object-tools">
            {# You can also give a name to that pattern and refer to it below using 'url' #}
            <li><a href="reset-password/" class="historylink">Reset password</a></li>

            <li><a href="history/" class="historylink">{% trans "History" %}</a></li>
            {% if has_absolute_url %}
                <li><a href="../../../r/{{ content_type_id }}/{{ object_id }}/" class="viewsitelink">
                    {% trans "View on site" %}</a>
                </li>
            {% endif%}
        </ul>
    {% endif %}{% endif %}
{% endblock %}

The result looks like this:
