The contains the directory server root DSE. The root DSE is the entry with the null DN (that is, a DN of "", containing zero RDN components) and exists to provide useful information about the capabilities of the server, including about the SASL mechanisms, controls, extended operations, and other types of features that the server supports. The OpenDS Directory Server root DSE entry contains operational attributes and are not be returned to the client unless they are explicitly requested. OpenDS also treats the root DSE as a parent to all other suffixes and has searches below the root DSE performed in all user backends (or using a configurable set of base DNs). ds-cfg-root-dse-backend top Specifies the set of base DNs that is used for singleLevel, wholeSubtree, and subordinateSubtree searches based at the root DSE. The set of all user-defined suffixes will be used. ds-cfg-subordinate-base-dn Indicates whether all attributes in the root DSE should be treated like user attributes (and therefore returned to clients by default) regardless of the directory server schema configuration. ds-cfg-show-all-attributes
