This evening I was thinking about the various security measures put in place at work. Although I use Kubuntu on my desktop, our network is a Windows/ActiveDirectory network.
The main thing I was thinking about was the password policy. ActiveDirectory has been set up to force a password change every 30 days. Of course this means fun for me once a month, since I don't log in via ActiveDirectory, and I only realise that my password has expired because I can no longer log into the bug tracker and I haven't had any new e-mails for two days.
