authenticate() function not working django.contrib.auth

I have a login_page function and in this function the authenticate() function returns a user object only if it is a superuser. For normal user, it returns None. Which is not as the documentation says.

def login_page(request):
    if request.user.is_authenticated(): # if user is already logged in
        return HttpResponseRedirect('/') # SHOULD BE DASHBOARD
    if request.method == 'POST':
        form = LoginForm(request.POST)
        if form.is_valid():
            username = form.cleaned_data['username']
            password = form.cleaned_data['password']
            seo_specialist = authenticate(username=username, password=password) #returns None
            if seo_specialist is not None:
                login(request, seo_specialist)
                return HttpResponseRedirect('/') # SHOULD BE DASHBOARD
            else:
                return render(request, 'login.html', {'form': form})
        else:
            return render(request, 'login.html', {'form': form})
    else: 
        form = LoginForm()
        context = {'form': form}
        return render(request, 'login.html', context)

Is there anything wrong with my code?

This is from django documentation. You seem to not have passed the request in ...authenticate(request, user...)

This example shows how you might use both authenticate() and login():

    from django.contrib.auth import authenticate, login

    def my_view(request):
        username = request.POST['username']
        password = request.POST['password']
        user = authenticate(request, username=username, password=password)
        if user is not None:
            login(request, user)
            # Redirect to a success page.
            ...
        else:
            # Return an 'invalid login' error message.
            ...

Try this:

def login_page(request):
    if request.method == "POST":
        username = request.POST['username']
        password = request.POST['password']
        seo_specialist = authenticate(username=username, password=password)
        if seo_specialist is not None:
            return HttpResponse("Signed in")
        else:
            return HttpResponse("Not signed in")
    else:
        # takes you to sign in form.

Basically replace is_valid and cleaned_data with request.POST and then authenticate. Also make sure you have

from django.contrib.auth import authenticate

at the top of your views.
