Personally, I set up all the LDAP trees I manage in this way. However, I've
encountered a bunch of installations where DNs are in the form cn=Full
Name,$rootdn or the like.

Also (correct me if I'm wrong), if you generate a DN in the code without
first performing a search, you're assuming that all users are directly under
a particular root DN; I would imagine that some organizations break users
off into different subtrees for logical and/or organizational purposes. For
example: uid=user1,ou=Engineering,o=BigCorp,c=US and
uid=user2,ou=Marketing,o=BigCorp,c=US. user1 and user2 are still in the same
namespace, but for whatever reason, they're split into two separate OUs.
