get Ad user using secure ldap

Anyone suggest me that how to get ad user from active directory using secure ldap in c#.

import ssl
from ldap3 import Server, Connection, SUBTREE

# LDAP server settings
ldap_server = 'ldaps://your_ldap_server:636'
ldap_user = 'username'  # Replace with your LDAP username
ldap_password = 'password'  # Replace with your LDAP password

# Search settings
base_dn = 'dc=your_domain,dc=com'
search_filter = '(sAMAccountName=user_to_find)'

# SSL context
ssl_context = ssl.create_default_context(cafile='path_to_trusted_root_certificate.pem')

# Create an LDAP connection
server = Server(ldap_server, use_ssl=True, get_info=Connection.ALL, ssl_context=ssl_context)
conn = Connection(server, user=ldap_user, password=ldap_password)

# Bind to the LDAP server
if not conn.bind():
    print('Failed to bind:', conn.result)
else:
    # Search for the user
    conn.search(search_base=base_dn, search_filter=search_filter, search_scope=SUBTREE, attributes=['sAMAccountName', 'mail', 'displayName'])
    
    # Print user attributes
    for entry in conn.entries:
        print('Username:', entry.sAMAccountName)
        print('Email:', entry.mail)
        print('Display Name:', entry.displayName)

# Close the connection
conn.unbind()
