PowerShell is capable of pulling list of 1492 records. When I using Python with ldap3 module I'm bumping into 1000 records limit. Please help me change Python code to exceed the limit.

PowerShell input: get-aduser -filter * -SearchBase "OU=SMZ USERS,OU=SMZ,OU=EUR,DC=my_dc,DC=COM" | Measure-Object

output: Count : 1492 Average : Sum : Maximum : Minimum : Property :

import json
from ldap3 import Server, \
Connection, \
AUTO_BIND_NO_TLS, \
SUBTREE, \
ALL_ATTRIBUTES

def get_ldap_info(u):
with Connection(Server('my_server', port=636, use_ssl=True),
                auto_bind=AUTO_BIND_NO_TLS,
                read_only=True,
                check_names=True,
                user='my_login', password='my_password') as c:

    c.search(search_base='OU=SMZ Users,OU=SMZ,OU=EUR,DC=my_dc,DC=com',
             search_filter='(&(samAccountName=' + u + '))',        
             search_scope=SUBTREE,
             attributes=ALL_ATTRIBUTES,
             size_limit = 0,
             paged_criticality = True,                 
             paged_size = None,
             #attributes = ['cn'],
             get_operational_attributes=True)        

    content = c.response_to_json()
result = json.loads(content)
i = 0
for item in result["entries"]:
    i += 1
print(i)  
get_ldap_info('*')

The solution is available in the following link.

This piece of code will fetch page by page.

from ldap3 import Server, Connection, SUBTREE
total_entries = 0
server = Server('test-server')
c = Connection(server, user='username', password='password')
c.search(search_base = 'o=test',
         search_filter = '(objectClass=inetOrgPerson)',
         search_scope = SUBTREE,
         attributes = ['cn', 'givenName'],
         paged_size = 5)
total_entries += len(c.response)
for entry in c.response:
    print(entry['dn'], entry['attributes'])
cookie = c.result['controls']['1.2.840.113556.1.4.319']['value']['cookie']
while cookie:
    c.search(search_base = 'o=test',
             search_filter = '(objectClass=inetOrgPerson)',
             search_scope = SUBTREE,
             attributes = ['cn', 'givenName'],
             paged_size = 5,
             paged_cookie = cookie)
    total_entries += len(c.response)
    cookie = c.result['controls']['1.2.840.113556.1.4.319']['value']['cookie']
    for entry in c.response:
        print(entry['dn'], entry['attributes'])
print('Total entries retrieved:', total_entries)
