Hi we want to disable users who are not active within 5 days . Is this possible how can we know which users are inactive for 5 days . we can probably disable by changing the u file so that the user cannot login anymore because if we change the user details inside Infor LN we need to convert to runtime.

Sounds like a rigid plan. Why would you do so?

What can be a plausible reasoning would be this: users that are logged in but their bshell has no activity for these 5 days... Their (server based) bshell may still running but the user did not logoff before closing the browser (and after that did not go back to the LN UI page).

Check the Session Timeout posts here if that is what you want.
