a node of your directory tree associated with a particular database
A distinguished name that identifies the top entry in a locally held directory hierarchy. Because of the relative naming scheme used in Lightweight Directory Access Protocol (LDAP), this suffix applies to every other entry within that directory hierarchy. A directory server can have multiple suffixes, each identifying a locally held directory hierarchy.
The name of the entry at the top of the directory tree, below which data is stored. Multiple suffixes are possible within the same directory. Each database only has one suffix.
