Re: [outkafe] Outkafe does not succeed in logging off if a user is playing videos...

Hi Ben,
Our windows userbase is fairly small so we don't really know the full
scale of potential issues -it's good to get this kind of feedback, I
don't use windows heavily myself but I believe my answers are not too
far off, I'd appreciate if somebody can give better details :)

I think that's about the only way - clearly these processes are
somehow overriding the outkafe client's system-calls to lock the
screen, and windows is allowing them to do so.
You could for an experiment see what happens if the video player
window is minimized, if that works - then you can probably rather
script it to just minimize all windows before executing the log-out ?

This is actually pretty standard procedure I think, outkafe doesn't
itself know how to prevent users from doing that, it's up to the
administrator to protect it.
