Enable autologin into flask app using active directory

Question

I have made flask web app meant to be used within my organisation.

My problem is currently the login works by requesting a username and password from the user which are then authenticated by an LDAP server.

I would like to be able to autologin a user immediately he gets onto the site since that's how other company internal websites work(these others were made in C# and php)

My main problem is:

• Is there a python package to get the client's windows username immediately he gets on to the site? and how would I use it

Requests-ntlm was once suggested but it has no documentation.

I have tried to look at several stack overflow questions but they do not address my problem eg link

Answer 1

It has taken me weeks to find the answer but Yes it is possible but you must configure the server where your app is hosted to allow this. In my case I was using IIS and enabled windows authentication. With this its surprisingly easy to get the active directory user name as it comes as part of the HTTP response:

from flask import request
username = request.environ.get('REMOTE_USER')
