Ну не знаю. У меня все работает.

# Connect to the LDAP server
server = Server(ldap_server, get_info=ALL)
conn = Connection(server, user=ldap_user, password=ldap_password, auto_bind=True)

# Search for users and groups
search_filter_users = '(&(objectClass=user)(sAMAccountName=))'

conn.search(base_dn, search_filter_users, attributes=['cn', 'memberOf'])
users = conn.entries

conn.search(base_dn, search_filter_groups, attributes=['cn'])
groups = conn.entries

# Create a list to store user data
user_data = []

# Extract user and group information
for user in users:
user_info = {
'username': user.cn.value,
'groups': [group.cn.value for group in groups if user.memberOf.value in group.entry_dn]
}
user_data.append(user_info)

# Create a pandas DataFrame
df = pd.DataFrame(user_data)

# Save the DataFrame as a JSON file
df.to_json('user_groups.json', orient='records', lines=True)

print("Data has been saved to user_groups.json")
