And a DN is not a partition, unless it names a partition. The partition concept is not linked to the DN, like a name is not linked to a human : 'winnie the pooh' is not a human only because it has a name... Think of it the other way : you first create the partition, then you name it. A partition is just a container for a tree, and it has a root, which name is used to describe the partition, and as we are in the ldap world, this name is a DN. This partition name will be the suffix of each entry's DN in this partition. >

Just think LDAP as a forest, with a lot of trees (DIT), each tree having one single big root (the suffix). The root is like a tree, but with no leaves. A partition is the whole tree, with the root(suffix) that we use to name the partition, and all the leaves. A leave can't be a part of more than one tree of course. Last point: during autumn, no gardener will pick the dead leaves on the ground ... Emmanuel
