Centrify reasonably says "are you sure about this????" when you try to set such long names, and can even mangle the names into the shorter structure for you. (I don't recommend this.) The boobytraps arise when someone's login in Active Directory is, for example, "NKadel", and you have your NIS/LDAP/whatever mapping think that your home directory and username is "NKadel", but your old NIS setup thought your login name was "nkadel". This way lies mixed case support madness, which is why "just write a shell script with ldapmodify" gets..... nastier than you might realize.
