python ldap"糟糕的搜索过滤器"错误

Question

这个过滤器在我的LDAP浏览器中运行得很好,python ldap不会把它拿起来:

(&(!objectClass=computer)(sn=*%s*))

导致:

Request Method: GET Request
URL: http://localhost:8000/ldap_find/%D0%B1%D0%BE%D0%BB%D0%BE%D1%82/
Django Version: 1.4
Exception Type: FILTER_ERROR
Exception Value: {'desc': 'Bad search filter'}

这是执行它的代码:

try:
    LDAPClient.connect()
    base = AUTH_LDAP_SEARCH_BASE
    scope = ldap.SCOPE_SUBTREE
    filter = '(&(!objectClass=computer)(sn=*%s*))' % search_string
    result_set = list()
    result = LDAPClient.client.search(base.encode(encoding='utf-8'), scope, filter.encode(encoding='utf-8'),['cn','mail'])
    res_type, res_data = LDAPClient.client.result(result)
    for data in res_data:
        if data[0]:
            result_set.append(data)
    return json.dumps(result_set)
except Exception, e:
    raise e
finally:
    LDAPClient.unconnect()

它可以很好地使用简单的过滤器,比如

filter = 'sn=*%s*' % search_string

所以我猜这是某种在ldap lib中转义的东西,但是还找不到root.

搜索过滤器语法不正确.使用(&(sn=*%s*)(!(objectClass=computer))).RFC4511和RFC4515中详细记录了搜索过滤器.
