Just another ehnancement of the original solution.

This accept multiple patterns and which is best also unnamed patterns written as relative URL wrapped in '"', like following:

{% url admin:clients_client_changelist as clients %}
{% url admin:clients_town_changelist as towns %}
{% url admin:clients_district_changelist as districts %}

Home
Clients
{% if request.user.is_superuser %}

    Settings
    

        
Towns
        
Districts
    

{% endif %}

Tag goes like this:

from django import template

register = template.Library()

@register.tag
def active(parser, token):
    args = token.split_contents()
    template_tag = args[0]
    if len(args) < 2:
        raise template.TemplateSyntaxError, "%r tag requires at least one argument" % template_tag
    return NavSelectedNode(args[1:])

class NavSelectedNode(template.Node):
    def __init__(self, urls):
        self.urls = urls

    def render(self, context):
        path = context['request'].path

        for url in self.urls:
            if '"' not in url:
                cpath = template.Variable(url).resolve(context)
            else:
                cpath = url.strip('"')

            if (cpath == '/' or cpath == '') and not (path == '/' or path == ''):
                return ""
            if path.startswith(cpath):
                return 'active'
        return ""
