Plugging Askbot into existing Django project, Aunthentication and integrating the users

pluggable
template_loaders
retag add tags

I installed askbot through pip into my existing local Django project. I merged the askbot settings & Uls files with my existing files. When I go to 127.0.0.1:8000/ its getting redirected to 127.0.0.1:8000/questions. And I can see all my existing users but no sign in is available. I see a lot of Url redirects not working because of reverse, like Reverse for 'home' with arguments '()' and keyword arguments '{}' not found. In my backend database all the tables are looking fine. But users are not integrated with askbot, also there is AttributeError with context_processor.py. How to allow my existing and future users, who are authenticated by my existing django project use askbot seamlessly? This is my template context tuple

TEMPLATE_CONTEXT_PROCESSORS = (
    #askbot
    #'django.contrib.auth.context_processors.auth',
    'django.core.context_processors.request',
    #"allauth.context_processors.allauth",
    #"allauth.account.context_processors.account",
    'askbot.context.application_settings',
    #'django.core.context_processors.i18n',
    'askbot.user_messages.context_processors.user_messages',#must be before auth
    'django.contrib.auth.context_processors.auth', #this is required for admin
    'django.core.context_processors.csrf', #necessary for csrf protection
