RootDSE (AD Schema)
In LDAP 3.0, rootDSE is defined as the root of the directory data tree on a directory server. The rootDSE is not part of any namespace. The purpose of the rootDSE is to provide data about the directory server. For more information about rootDSE, see Serverless Binding and RootDSE in the Active Directory SDK documentation.
rootDSE contains the following attributes. All attributes are single-valued unless otherwise noted.
