AnonymousUser after login about django-cas-ng

[shacker]

Additional info: I actually use django_cas_ng on two sites, and this problem is only happening on one of them.

Python 2.7 + Django 1.8.2 = broken
Python 3.5 + Django 1.9.1 = working

working fine with v3.5.3 + python 2.7 + Django 1.7.7

Hmm, interesting. It definitely broke for me on update. Our implementation is very straightforward - nothing fancy. The only settings I'm using are:

CAS_SERVER_URL = 'https://cas.ourdomain.edu/cas/login'
CAS_ADMIN_PREFIX = '/admin'
CAS_LOGOUT_COMPLETELY = True
CAS_REDIRECT_URL = '/'

If this is a result of a bug elsewhere in our project code, I don't know where to begin to look. Ideas?

[nitmir]

right now, I really don't known. There is a lot of changes since v3.4.2 (the main one I think being putting all CAS logic in a external lib https://github.com/python-cas/python-cas). I'll try tomorrow on Django 1.8.2 to see if I can reproduce the bug.

[nitmir]

sorry but I cannot reproduce

mkdir /tmp/testcas
virtualenv /tmp/testcas
. /tmp/testcas/bin/activate
pip install Django==1.8.2
pip install django-cas-ng
cd /tmp/testcas/
django-admin startproject testproject
# setup django-cas-ng by editing testproject/settings.py and testproject/urls.py
django-admin startapp testapp
# add testapp to testproject/settings.py and testproject/urls.py and setup a trivial view

My trivial view is

from django.contrib.auth.decorators import login_required

@login_required
def test(request):
    raise ValueError("username: %s is auth %s" % (request.user, request.user.is_authenticated()))

And it effectively raise my current username and True and not AnonymousUser.
for info :

$ pip freeze
Django==1.8.2
argparse==1.2.1
django-cas-ng==3.5.3
python-cas==1.1.0
six==1.10.0
wsgiref==0.1.2

Just note that your CAS_SERVER_URL should probably be 'https://cas.ourdomain.edu/cas/' without the login but I do not think it really matter as I have tested too with a /login in my CAS url and it worked just fine…

Interesting. Well, thank you very much for investigating! I'm not sure where to begin troubleshooting this one, but at this point it appears to definitely be somehow related to my codebase. I'll close this and leave a comment in the future when I figure it out. Thanks.

I had the same issue,
python 2
Django 1.8
django-cas-ng 3.5.3

Unsure of what exactly the problem was, but commenting/removing the following lines fixed the issue: https://github.com/mingchen/django-cas-ng/blob/master/django_cas_ng/views.py#L64-65

Not saying its a good idea, but it worked for me.
