R

RDN (LDAP)

referral (LDAP)

The Relative Distinguished Name (frequently but incorrectly written as Relatively Distinguished Name). The name given to an attribute(s) that is unique at its level in the hierarchy. RDNs may be single valued or multi-valued in which case two or more attributes are combined using '+' (plus) to create the RDN e.g. cn+uid. The term RDN is only meaningful when used as part of a DN to uniquely describe the attributes on the path UP the DIT from a selected entry (or search start location) to the directory root (or more correctly the Root DSE). More info.

An operation in which the LDAP server returns to an LDAP client the name (typically in the form of an LDAP URL) of another LDAP server that might be able to provide the information requested by the LDAP client.

Remote Authentication Dial-In User Service (RADIUS)

RADIUS is a client/server protocol and software that enables remote access servers to communicate with a central server to authenticate dial-in users and authorize their access to the requested system or service. RADIUS allows a company to maintain user profiles in a central database that all remote servers can share. It provides better security, allowing a company to set up a policy that can be applied at a single administered network point. Having a central service also means that it's easier to track usage for billing and for keeping network statistics.

root (LDAP)	The root entry (a.k.a base, suffix) is one of many terms used to describe the topmost entry in a DIT.
	The Root DSE is a a kind of super root.
Root DSE (LDAP)	Conceptually the top most entry in a LDAP hierarchy - think of it as a super root and normally
	invisible i.e. not accessed in normal operations. Sometimes confused with root or base or suffix. DSE
	stands for DSA Specific Entry and DSA in turn stands for Directory System Agent (any directory
	enabled service providing DAP or LDAP access). Information about the rootDSE may be obtained in
	OpenLDAP by querying the OpenLDAProoDSE classobject and will provide information about
	protocol versions supported, services supported and the naming-context(s) or DIT(s) supported.
rootdn (LDAP)	The rootdn is a confusingly named directive in the slapd.conf file which defines a superuser which can
	bypass normal directory access rules.
