在Django中修改Active Directory用户

Question

所以我试图修改我的活动目录中的用户。截至目前，我可以作为AD用户登录，但是当我尝试编辑我的配置文件时，它不会在AD中实现。

我使用django-auth-ldap作为AD后端。

我与具有读写权限的用户建立了连接。

AUTH_LDAP_SERVER_URI = "ldap://192.168.1.12"

AUTH_LDAP_BIND_DN = "user"
AUTH_LDAP_BIND_PASSWORD = "password"
AUTH_LDAP_CONNECTION_OPTIONS = {
    ldap.OPT_DEBUG_LEVEL: 1,
    ldap.OPT_REFERRALS: 0
}
AUTH_LDAP_USER_SEARCH = LDAPSearch("DC=sb,DC=ch", ldap.SCOPE_SUBTREE, "(sAMAccountName=%(user)s)")

# Set up the basic group parameters.
AUTH_LDAP_GROUP_SEARCH = LDAPSearch("DC=sb,DC=ch", ldap.SCOPE_SUBTREE, "(objectClass=group)")
AUTH_LDAP_GROUP_TYPE = NestedActiveDirectoryGroupType()


# What to do once the user is authenticated
AUTH_LDAP_USER_ATTR_MAP = {
    "first_name": "givenName",
    "last_name": "sn",
    "email": "mail"
}

AUTH_LDAP_USER_FLAGS_BY_GROUP = {
    "is_active": "CN=ipa-users,cn=users,DC=sb,DC=ch",
    "is_staff": "CN=ipa-users,cn=users,DC=sb,DC=ch",
    "is_superuser": "CN=ipa-users,cn=users,DC=sb,DC=ch"
}

# This is the default, but be explicit.
AUTH_LDAP_ALWAYS_UPDATE_USER = True

# Use LDAP group membership to calculate group permissions.
AUTH_LDAP_FIND_GROUP_PERMS = True

# Cache settings
AUTH_LDAP_CACHE_GROUPS = True
AUTH_LDAP_GROUP_CACHE_TIMEOUT = 3600

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

那么我必须设置或获取任何内容？

这是我的edit_profile.html：

<form method="post">
        {% csrf_token %}

        <label for="first_name">Vorname </label>
        <input style="margin-bottom: 1em;" id="first_name" class="form-control" type="text" name="first_name" value="{{ user.first_name }}"><br>
        <label for="last_name">Nachname </label>
        <input style=" margin-bottom: 1em;" id="last_name" class="form-control" type="text" name="last_name" value="{{ user.last_name }}"><br>
        <label for="email">E-Mail </label>
        <input style="margin-bottom: 1em;" id="email" class="form-control" type="email" required=True unique=True name="email" value="{{ user.email }}"><br>

        <button class="btn btn-success btn-sm" type="submit">Bestätigen</button>

Answer 1

It is impossible with only django-auth-ldap

粗略的猜测显示你正在使用django-auth-ldap（我更新了你的问题）。一眼就可以看出它只有一个后端，不能做任何其他事情。

如果您确实想要更新AD中的某些数据，则需要自己完成。我正在使用python-ldap3，我可以为此推荐。它还包括一些专门针对AD的助手。

Upd: as requested, an example using python-ldap3

类似的东西，不确定下面的代码是否有效（它是现有代码的混搭）。但它应该让你知道你应该做什么。欢迎来到LDAP的地狱。

import ldap3

conn = ldap3.Connection(
    server="ldaps://foobar",
    user="username@domain",  # normally full DN, but AD supports this format as well
    password="password",
    auto_bind=ldap3.AUTO_BIND_NONE,
    authentication=ldap3.SIMPLE,
    raise_exceptions=True,
    auto_referrals=False,  # 90% you want it set to False
    receive_timeout=10,  # seconds, exception afterwards
)

conn.start_tls()
conn.bind()

search = conn.extend.standard.paged_search(
    search_base="dc=domain",
    search_filter="(userPrincipalName=username@domain)",  # or (cn=username) or (sAMAccountName=username) or whatever
    search_scope=ldap3.SUBTREE,
    attributes=ldap3.ALL_ATTRIBUTES,
    dereference_aliases=ldap3.DEREF_NEVER,
    generator=True,
)

entries = [entry for entry in search if entry["type"] == "searchResEntry"]  # not sure how to get rid of all the aliases otherwise

assert len(entries) is 1, "got {0} entries".format(len(entries))
entry = entries[0]

dn = entry["dn"]

changes = {
    "attributeName": [
        [ldap3.MODIFY_DELETE, ["old value 1", "old value 2",]],
        [ldap3.MODIFY_ADD, ["a new value"]],
    ]
}

conn.modify(dn, changes)

conn.unbind()

Answer 2

并非不可能，但并不容易。

首先，您需要对用户进行身份验证或在LDAP中找到他。例：

user = authenticate(
    username=request.user.username,
    password=request.POST['password']
)

现在，用户有一些request.user对象没有的属性，如ldap_user。此属性可用于修改密码，例如：

# remember to add: import ldap.modlist as modlist

pwd = "new password"
ldif = modlist.modifyModlist(
    {'userpassword': user.ldap_user.attrs['userpassword']},
    {'userpassword': [pwd.encode()]}
)
user.ldap_user.connection.modify_s(user.ldap_user.dn, ldif)

就是这样。
