Novell’s eDirectory has limitation of CN length to 64 characters. That is enough for common objects.
However, in my application I auto-generated CN out of some long string. I wanted management groups for user containers of a deep tree (5 levels e.g. ou=Happy Branch,ou=Berline,ou=DE,ou=Europe,o=Company). For some practical and user’s reasons I didn’t want to copy the container tree structure, so I created objects at the same level with CN made out in reverse – e.g. Europe-DE-Berlin-Happy Branch. But for some groups their CN got over 64 letters, and that failed. So I created region containers for them and then I created the groups under those region containers, with CN e.g. DE-Berlin-Happy Branch. Problem solved!
