This happened where I work. An inexperienced team was making changes to a shared code base. They made changes to make usernames case insensitive, without thinking about them ready being case sensitive. So if you logged in with user CAT123, you might get cat123's info. And then I was left on the team that had to clean up their mess and find and understand the impact.
Whoever ever thought that case sensitivity is a good idea ever in any place or time whatsoever, can go to hell. Including but not limited to Unix systems.
I hadn't given it much thought as so many of the legacy systems I worked with were case sensitive. But I'm with you. Except for passwords.
