I am using Django 1.5. I have the following model:

class User(AbstractBaseUser):
    #id = models.IntegerField(primary_key=True)
    #identifier = models.CharField(max_length=40, unique=True, db_index=True)
    username = models.CharField(max_length=90, unique=True, db_index=True)
    create_time = models.DateTimeField(null=True, blank=True)
    update_time = models.DateTimeField(null=True, blank=True)
    email = models.CharField(max_length=225)
    password = models.CharField(max_length=120)
    external = models.IntegerField(null=True, blank=True)
    deleted = models.IntegerField(null=True, blank=True)
    purged = models.IntegerField(null=True, blank=True)
    form_values_id = models.IntegerField(null=True, blank=True)
    disk_usage = models.DecimalField(null=True, max_digits=16, decimal_places=0, blank=True)
    objects = UserManager()
    USERNAME_FIELD = 'email'
    class Meta:
        db_table = u'galaxy_user'

I am getting this error when running ./manage.py syncdb:

FieldError: Local field 'password' in class 'User' clashes with field of similar name from base class 'AbstractBaseUser'

I tried removing the password field from the model but it is not authenticating even if the password field is removed from the model. I am using my custom Django authentication:

class AuthBackend:
    def authenticate(self, username=None, password=None):
        if '@' in username:
            kwargs = {'email': username}
        else:
            kwargs = {'username': username}
        try:
            user = User.objects.get(**kwargs)
            if user.check_password(password):
                return user
        except User.DoesNotExist:
            return None

    def get_user(self, user_id):
        try:
            return User.objects.get(pk=user_id)
        except User.DoesNotExist:
            return None

what's the error you get once you remove the password field?Calendar
I am getting not any error. Even if I supply the correct password it's returning None that's why I am not been able to login.Integer

Field name “hiding” is not permitted in Django unlike with normal python inheritance

just use the password field provided by the abstract user and do any custom saving/checks in the save method or in a form/api

read here for more info on this:
