Flask LDAP3 Auth 청사진이 초기화되지 않은 ASN.1 값과 함께 실패합니다.

Question

LDAP3 인증을위한 플라스크 청사진을 작성하려고합니다. 나는 표준 플라스크 응용 프로그램과 같은 코드를 사용하는 경우, 예상대로 모든 것이, 바인드는 성공적으로 작동하고 사용자 인증도 성공 :

DEBUG:root:Validating LDAPLoginForm against LDAP 
DEBUG:flask_ldap3_login:Opening connection with bind user 'XXXX@XXXX.COM' 
DEBUG:flask_ldap3_login:Successfully bound to LDAP as 'XXXX@XXXX.COM' for search_bind method 
DEBUG:flask_ldap3_login:Performing an LDAP Search using filter '(&(objectclass=person)(sAMAccountName=YYYY))', base 'ou=Users,ou=XXXX,dc=XXXX,dc=COM', and scope 'SUBTREE' 
DEBUG:flask_ldap3_login:Opening connection with bind user 'CN=YYYY,OU=Admin Users,OU=Users,OU=XXXX,DC=XXXX,DC=COM' 
DEBUG:flask_ldap3_login:Directly binding a connection to a server with user:'CN=YYYY,OU=Admin Users,OU=Users,OU=XXXX,DC=XXXX,DC=COM' 
DEBUG:flask_ldap3_login:Authentication was successful for user 'YYYY' 

하지만 최대한 빨리 청사진으로 바꿀 같이

DEBUG:root:Validating LDAPLoginForm against LDAP 
DEBUG:flask_ldap3_login:Opening connection with bind user 'XXXX@XXXX.COM' 
DEBUG:flask_ldap3_login:Destroying connection at <0x7f181f9ee2b0> 
ERROR:flask_ldap3_login:Uninitialized ASN.1 value ("__len__" attribute looked up) 

:

from flask import Flask 

app = Flask(__name__) 
app.config.from_object('config') 

from app.ldauth.views import auth_blueprint 
app.register_blueprint(auth_blueprint) 

그리고 응용 프로그램/ldauth/views.py을 다음과 같이

이것이 virtualenv의 문제였습니다. 오늘 아침에 새로운 virtualenv를 만들었고 코드를이 코드로 옮겼습니다. 예상대로 작동합니다.
