LDAP connect succeeded
LDAP user attributes empty
[29/Jan/2021 12:01:14] "POST /admin/login/?next= /admin/ HTTP/1.1" 200 2359

Answer 1

LDAP_AUTH_OBJECT_CLASS = "Users"

in LDAP this class is usually just user (objectclass = user)

LDAP_AUTH_USER_LOOKUP_FIELDS = ("username")

If I understand correctly, you are trying to get the "username" attribute, which does not exist. It seems to me that sAMAccountName should be here
