In general, it seems to me that many information security professionals strengthen security for the sake of security itself, forgetting for a long time about its original purpose. I have seen situations where password checking rules were so complex that employees had to collectively come up with predictable password generation schemes, which meant that passwords were not only predictable in the historical context of the individual user, but of the group as a whole.

Slightly off-topic, but I once ran into a system that would not allow kk1bsk#$ as a password because it contained a dictionary word.
Still wondering what dictionary they were using...
