我正在使用 django-auth-ldap 进行我的 django 身份验证，并即时创建用户。

在我的 settings.py

AUTHENTICATION_BACKENDS = (
    'django_auth_ldap.backend.LDAPBackend',
    'django.contrib.auth.backends.ModelBackend',
)

AUTH_LDAP_USER_SEARCH = LDAPSearch(
    "ou=clients,dc=oasiswork,dc=fr",
    ldap.SCOPE_SUBTREE,
    "(mail=%(user)s)")

AUTH_LDAP_USER_ATTR_MAP = {
    "username"  : "mail",
    "id"        : "uid",
    "first_name": "givenName",
    "last_name" : "sn",
    "mail"      : "mail"
}

现在我的测试用例是：

LDAPBackend().populate_user('test1@example.net')
LDAPBackend().populate_user('test2@example.net')

是的，我确实想从 ldap 设置 ID。

我只有一个来自标准用户模型的用户，其 ID 与 LDAP 没有可能的冲突。

问题是，如果我不把这"id" : "uid",条线放在设置中，我的测试用例就会很好。

但是，如果我保留这条线，它会在第一次创建用户时失败：

django.db.utils.IntegrityError: column username is not unique

这似乎与我正在尝试做的事情完全无关（与用户名无关，并且用户配置在没有“id”的情况下工作AUTH_LDAP_USER_ATTR_MAP）
