eDirectory as a directory provides more services than are available with the standard LDAP functions or Java classes. LDAP v3 provides a method for extending its functionality through LDAP controls and extensions. The LDAP server in NDS eDirectory contains a registration mechanism for LDAP extensions. In future releases, Novell will write LDAP extensions to access such features as ACLs, replication, partition, and synchronization services. Novell is currently working with standards bodies to define ways to access such services.
For a list of currently supported controls, query the rootDSE.
The LDAP control “2.16.840.1.113719.1.27.101.57” (CONTROL_REQ_DISABLE_COUNT) in the eDirectory LDAP server allows you to control the behavior of counting results as part of the VLV (Virtual List View) control. This control disables counting of results for VLV control. Prior to this, each result requires evaluation against the specified filter. This control helps to improve the VLV control performance by returning the search results much faster.
