Flask/Python decoding username NTLM or Negotiate Authentication Header -

i have flask app hosted in iis in our intranet. in flask, i'm able www-authenticate header, need determine windows username. did have basic authentication enabled , able parse out username via method, want transparent user. in ie have option set auto login intranet sites they're not prompted username , password.

i able string can either begin ntlm or negotiate (depending on setting in iis) , long auth string. reliable way can decode in python/flask?

got it.

class remoteusermiddleware(object):     def __init__(self, app):         self.app = app     def __call__(self, environ, start_response):         user = environ.pop('http_x_proxy_remote_user', none)         environ['remote_user'] = user      return self.app(environ, start_response)  app.wsgi_app = remoteusermiddleware(app.wsgi_app) 

then in view doing this:

username = str(request.environ.get('logon_user'))
