Yes, I remember that. One of my first jobs out of school was a sysadmin for various unix machines (Sun, DEC, HP, and others I've forgotten.) FlexLM was everywhere. Annoying to configure. I'd install it, and have no way to test if it was working, since I didn't actually run any of that software. I'd email some people in another group to get help testing it, and would never hear back. The joys of corporate america. I moved on pretty quick.
