Python使用ldap3认证

一、安装ldap3模块（python版本为python3以上，Django=1.11.8）
pip install ldap3

二、相关代码

from ldap3 import Server, Connection, ALL, SUBTREE, ServerPool,ALL_ATTRIBUTES

LDAP_SERVER_POOL = ["AD_IP1", "AD_IP2"]

LDAP_SERVER_PORT = 389

ADMIN_DN = "[email protected]"

ADMIN_PASSWORD = "xxxxxxx"

SEARCH_BASE = "ou=Users,dc=domainname,dc=com"

def ldap_auth(username, password):

    ldap_server_pool = ServerPool(LDAP_SERVER_POOL)

    conn = Connection(ldap_server_pool, user=ADMIN_DN, password=ADMIN_PASSWORD, check_names=True, lazy=False, raise_exceptions=False)

    conn.open()

    conn.bind()

    res = conn.search(

        search_base = SEARCH_BASE,

        search_filter = '(sAMAccountName={})'.format(username),

        search_scope = SUBTREE,

        attributes = ['cn', 'givenName', 'mail', 'sAMAccountName','department','manager'],

        #ALL_ATTRIBUTES：获取所有属性值

        # attributes=ALL_ATTRIBUTES,

        paged_size = 5

    )

    if res:

        entry = conn.response[0]

        # print(entry)

        dn = entry['dn']

        attr_dict = entry['attributes']

        # check password by dn

        try:

            conn2 = Connection(ldap_server_pool, user=dn, password=password, check_names=True, lazy=False, raise_exceptions=False)

            conn2.bind()

            if conn2.result["description"] == "success":

                print((True,attr_dict["sAMAccountName"],password, attr_dict["mail"], attr_dict["cn"],attr_dict["department"], attr_dict["givenName"]))

                return (True, attr_dict["sAMAccountName"],password, attr_dict["mail"],attr_dict["cn"],attr_dict["department"],attr_dict["givenName"])

            else:

                print("auth fail")

                return (False, None, None, None)

        except Exception as e:

            print("auth fail")

            return (False, None, None, None)

    else:

        return (False, None, None, None)

if __name__ == "__main__":

    ldap_auth("administrator", "xxxxxxxx")
