python - LDAP3 模块获得超过 1000 个结果或备选方案

Question

# import class and constants
from ldap3 import Server, Connection, ALL, SUBTREE

# define the server
s = Server(host='xyz', port=xxxx, use_ssl=True, get_info='ALL')
c = Connection(s, auto_bind='NONE', version=3, authentication='ANONYMOUS', client_strategy='SYNC', auto_referrals=True, check_names=True, read_only=False, lazy=False, raise_exceptions=False)

c.bind()
results = c.extend.standard.paged_search(
    search_base = 'Ou=XYZ,dc=org,dc=com',
    search_filter = '(AppID=*)',
    search_scope = SUBTREE,
    get_operational_attributes=True,
    attributes=['*'],
    generator=True,
    paged_size=None
)
i=0

for entries in results:
    print(entries)
    i+=1
print(i)

我正在尝试连接到特定端口上的服务器并进行匿名 SSL 身份验证。我编写了上面的脚本来获取“Ap​​pID = *”的结果。我只能打印 1000 条记录，然后遇到以下错误:

Traceback (most recent call last): File "C:/Fetch data.py", line 43, in for entries in results: File "C:\Users\xyz\AppData\Local\Programs\Python\Python36\lib\site-packages\ldap3\extend\standard\PagedSearch.py", line 75, in paged_search_generator raise LDAPOperationResult(result=result['result'], description=result['description'], dn=result['dn'], message=result['message'], response_type=result['type']) ldap3.core.exceptions.LDAPSizeLimitExceededResult: LDAPSizeLimitExceededResult - 4 - sizeLimitExceeded - None - None - searchResDone - None

我已经尝试过提供的解决方案 Conquering Active Directory's 1000 record limit

我试过浏览文档 LDAP3 Docs 但没有成功。有没有办法读取完整的输出。 (我想有超过 5k 条记录)

这里的问题是您的代码会生成一个生成器对象。

from ldap3 import Server, Connection, SUBTREE
import ldap3
total_entries = 0
# define the server
s = Server(host='xyz', port=xxxx, use_ssl=True, get_info=ldap3.NONE)
c = Connection(s,authentication='ANONYMOUS') 
# subtitute your filter here 
filter = '(&(objectClass=group)(sAMAccountName=))'
entry_generator = c.extend.standard.paged_search(search_base = 'Ou=XYZ,dc=org,dc=com',
                                                 search_filter = filter,
                                                 search_scope = SUBTREE,
                                                 get_operational_attributes=True,
                                                 attributes = ['*'],
                                                 paged_size = 1000,
                                                 generator=True)
for entry in entry_generator:
    total_entries += 1
    print(entry['dn'], entry['attributes'])
print('Total entries retrieved:', total_entries) 

这应该为您提供所需的所有详细信息。
