I need to connect to a LDAP server using Python (Version 3.8.8) and I've already tried to replicate some examples such as those showed in the link bellow but none of them are working for me. I either get (TypeError: iter() returned non-iterator of type 'NoneType') or (PyAsn1Error: Attempted "__iter__" operation on ASN.1 schema object). It seems like ldap3 and python-ldap used in the examples were not updated to work with python 3.8.8. I would be very pleased if anyone could give me a real example of another existing library to connect a LPDAP server or help me with this issue.

my test error for the example in link 3:
