34408	Authorization in Custom Authentication Backend does not work	Vivek Kumar Singh	nobody	"I was experimenting with `has_perm` and `user_can_authenticate` functions in my custom authentication backend when I found out these function aren't even executing during the Authentication process. I tries putting print statements but there was no output in the log screen. I also tried using example suggested in Django Documentation (https://docs.djangoproject.com/en/4.1/topics/auth/customizing/#handling-authorization-in-custom-backends) but it still didn't work.

Here is my code:

{{{#!python
class EmailBackend(BaseBackend):
    def authenticate(self, request, username=None, password=None):
        try:
            user = User.objects.get(email=username)
            if user.check_password(password):
                return user
            return None
        except User.DoesNotExist:
            return None

    
    def get_user(self, user_id):
        try:
            return User.objects.get(pk=user_id)

        except User.DoesNotExist:
            return None

    def has_perm(self, user_obj, perm, obj=None):
        print(""hello"")
        return True
}}}

and logs 

{{{
[12/Mar/2023 00:01:05] ""GET /login HTTP/1.1"" 200 861
[12/Mar/2023 00:01:16] ""POST /login HTTP/1.1"" 302 0
[12/Mar/2023 00:01:16] ""GET / HTTP/1.1"" 200 370
}}}

as you can see there was no output saying ""hello"".
please explain what is the use of has_perm and other authorization functions in django anyway."	Bug	closed	contrib.auth	4.1	Normal	invalid	authentication, authorization		Unreviewed	0	0	0	0	1	0
