Hi @Quazz,
We tried to reproduce the issue but need more details on step# 4 "Call admin session cleaner function".
it would be great if you can specify method signature, calling methods.

Thanks

I have edited the issue with more precise steps.

To clarify:

The bug seems to come from: https://github.com/magento/magento2/blob/2.4-develop/app/code/Magento/Security/Model/AdminSessionsManager.php#L279

Simple enough fix would be to change it to be more like: https://github.com/magento/magento2/blob/2.4-develop/app/code/Magento/Security/Model/AdminSessionsManager.php#L112 of the same class

As far as I understand, a session should only be considered expired if the admin session lifetime threshold has been met, not any sooner.

Something I forgot (didn't think about it).

I suppose this also means it won't clean the sessions if the session timer is defined as SMALLER than the constant.
