"Directory Tree Overview". This section describes the concept of a directory tree. Also included is advice on how to plan and define your directory tree's suffix.
"Branching Your Directory Tree". This section describes the branching strategies and the distinguished name designs that you should use with your directory tree.
"Naming Person Entries". This section describes the distinguished name conventions that you should use for directory entries that represent people.
"Naming Non-Person Entries". This section describes the distinguished name conventions that you should use for directory entries that do not represent people.
Try to use only the traditional attributes (shown in Table 6.1). While not strictly necessary, using the traditional attributes means that you have the greatest likelihood of retaining interoperability with third-party LDAP clients. Using the traditional attributes also means that they will be known to your directory schema, which is desirable when it comes time to build the entries associated with the DN.
In "Selecting a Suffix", you are advised to avoid rooting your directory tree in a country designator. This is especially true if your enterprise is international in scope.
