Custom activation email not working in Django

Deploying a Django app via Apache on Windows Server
I am moving to Python/Django from .NET for my upcoming project. Traditionally, using IIS is easy for us due to Windows Authentication and impersonation. However, without IIS, it is a totally new world for us as we have to deal with Kerberos directly. So far i have managed to deployed a Django app on Apache2.4 on my Windows Server VM. I am trying to get the client web browser to negotiate with my Apache web server to no avail. I have also tried to look into mod_auth_kerb, however it seems that it is mainly compatible with Linux: also checked out mod_spnego with little success. I would like to find out how I can acquire the user’s ID (so that i can make use of it for Oracle Kerberos login) when he access the website hosted on Apache. Thanks -

Should there be separate Django app for each user type in a Django project?
I have got multiple user types in my Django project(around 4 to 5). I am stuck with the code layout. Is it a good design to have a separate Django app for each user type? As each user will be redirected to different interface after login and each user will have different tasks to perform. Also i am thinking to make one common app for common functionality like the login, logout and also its models.py file will contain all the common models used by other apps? Please suggest the best code design for such case. -

Is perfoming calculations part of the backend?
Good night, I'm making a system using Django on the back end. I came up with a theoretical question, I am performing some calculations between existing inputs using JavaScript, and the values of those inputs I save in the database with Django. My question is, are these calculations I make between inputs part of the Backend? Or just the moment I use Django to save them? Thanks if you can help me! -

Django - manage.py collectstatic saving to the wrong folder

The staticfiles folder in addition to files from static folder also contains a tz_detect folder (from static assets from 3rd party package), an admin folder, and a staticfiles.json -
