django-crowd-auth's Issues

Release 0.8.0 with pip 10 fix

Would you mind creating release 0.8.0 with the pip 10 fix and also push this to pip?

Many thanks in advance!

No module named django_crowd_auth

We tried to include this into our zulip instance but we keep getting Internal Server Errors.

In the file /etc/zulip/settings.py we made the following changes:

AUTHENTICATION_BACKENDS = (
django_crowd_auth.backends.Backend
# 'zproject.backends.EmailAuthBackend', # Email and password; just requires SMTP setup
# 'zproject.backends.GoogleMobileOauth2Backend', # Google Apps, setup below
# 'zproject.backends.GitHubAuthBackend', # GitHub auth, setup below
# 'zproject.backends.AzureADAuthBackend', # Microsoft Azure Active Directory auth, setup below
'zproject.backends.ZulipLDAPAuthBackend', # LDAP, setup below
# 'zproject.backends.ZulipRemoteUserBackend', # Local SSO, setup docs on readthedocs
)

CROWD_CLIENT = {
'crowd_url': 'https://crowd.foo.bar',
'app_name': 'foo',
'app_pass': 'bar',
'ssl_verify': '/etc/pki/tls/certs/ca-bundle.crt',
'timeout': 10,
}
CROWD_USERS_ARE_STAFF = True

And in /home/zulip/deployments/current/zprojects/settings.py

MIDDLEWARE = (
# With the exception of it's dependencies,
# our logging middleware should be the top middleware item.

'two_factor.middleware.threadlocals.ThreadLocals', # Required by Twilio
# Needs to be after CommonMiddleware, which sets Content-Length
'zerver.middleware.FinalizeOpenGraphDescription',
)

INSTALLED_APPS = [

We are using Python 3.5 and installed with pip3.

Can Someone help us?

Middleware initialisation breaks app re- load/start if Crowd is unreachable

client.get_cookie_config() does a request to Crowd for the cookie settings:

def sso(get_response):
    """Crowd SSO middleware.
    """
    client = Client.from_settings()
    cookie_config = client.get_cookie_config()
    cookie_name = cookie_config['name']
    cookie_domain = cookie_config['domain']
    cookie_secure = cookie_config['secure']
    LOGGER.debug('Crowd cookie config %r', cookie_config)

This request is retried N times and in case Crowd is unreachable, results in a max retries uncaught exception being thrown, causing the app re- load/start to fail.

Expected behaviour is that the middleware fails gracefully and allows the app to re- load/start, independent of Crowd being up.

I will put up a PR with a fix.

Assuming that request is always an object is incorrect

https://docs.djangoproject.com/en/2.0/topics/auth/customizing/#authentication-backends

request is an HttpRequest and may be None if it wasn’t provided to authenticate() (which passes it on to the backend).

Environment:


Request Method: POST
Request URL: https://hostname/accounts/login/

Django 2.x.x support

It doesn't appear that this supported Django 2.x at this time?

pip 10.x install breaks on unused parse_requirements import in setup.py

pip 10.X+ has moved the module pip.req to pip._internal.req, which causes setup.py to fail for pip 10.X+ on this include:

from pip.req import parse_requirements

Causes the following error:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File ".../django-crowd-auth/setup.py", line 4, in <module>
    from pip.req import parse_requirements
ImportError: No module named 'pip.req'

https://github.com/pmuller/django-crowd-auth/blob/master/setup.py#L4

Additionally, the parse_requirements function is not used as far as i can tell, so it seems this entire import can be removed.
