python-ldap 中 SimplePagedResultsControl 中的 'criticality' 属性是什么?

What is the 'criticality' attribute in SimplePagedResultsControl in python-ldap?

我正在使用 python-ldap 进行 LDAP 搜索的分页。
我在网上找了很多类似的参考资料,都设置了:
page_control = SimplePagedResultsControl(True, size={some_size}, cookie='')
例如:https://medium.com/@alpolishchuk/pagination-of-ldap-search-results-with-python-ldap-845de60b90d2
我查看了 python-ldap 的文档,没有找到有用的解释:
https://www.python-ldap.org/en/latest/reference/ldap-controls.html#ldap.controls.libldap.SimplePagedResultsControl

我找到了答案:https://www.rfc-editor.org/rfc/rfc2696

If the server does not support pagedResultsControl, 
the server MUST return an error of unsupportedCriticalExtension if the client
requested it as critical, otherwise the server SHOULD ignore the control.
