My new favorite is the minimum time between password changes. My last 2 jobs set it to 24 hours, so IT guy gives you the temp password and you can't change it for 24 hours. But wait, when you try to change it the error you get is "doesn't meet your organization's minimum complexity requirements" which does not help AT ALL and the IT guy thinks you're an idiot because you can't figure out the complexity requirements. What a great feature!
