PTA directory
server
In pass-through authentication (PTA), the PTA Directory Server is the server that sends (passes
through) bind requests it receives to the authenticating directory server.
PTA LDAP URL In pass-through authentication, the URL that defines the authenticating directory server, pass-through
subtree(s), and optional parameters.
R
RAM Random access memory. The physical semiconductor-based memory in a computer. Information
stored in RAM is lost when the computer is shut down.
RDN The name of the actual entry itself, before the entry's ancestors have been appended to the string
to form the full distinguished name. Also relative distinguished name.
read-only replica A replica that refers all update operations to read-write replicas. A server can hold any number
of read-only replicas.
read-write replica A replica that contains a master copy of directory information and can be updated. A server can
hold any number of read-write replicas.
referential integrity Mechanism that ensures that relationships between related entries are maintained within the
directory.
referral (1) When a server receives a search or update request from an LDAP client that it cannot process,
it usually sends back to the client a pointer to the LDAP sever that can process the request.
(2) In the context of replication, when a read-only replica receives an update request, it forwards
it to the server that holds the corresponding read-write replica. This forwarding process is called
a referral.
relative
distinguished
name
See RDN.
replica A database that participates in replication.
replica-initiated
replication
Replication configuration where replica servers, either hub or consumer servers, pull directory
data from supplier servers. This method is available only for legacy replication.
replication Act of copying directory trees or subtrees from supplier servers to replica servers.
replication
agreement
Set of configuration parameters that are stored on the supplier server and identify the databases
to replicate, the replica servers to which the data is pushed, the times during which replication
can occur, the DN and credentials used by the supplier to bind to the consumer, and how the
connection is secured.
RFC Request for Comments. Procedures or standards documents submitted to the Internet community.
People can send comments on the technologies before they become accepted standards.
role An entry grouping mechanism. Each role has members, which are the entries that possess the
role.
role-based
attributes
Attributes that appear on an entry because it possesses a particular role within an associated
CoS template.
root The most privileged user available on UNIX machines. The root user has complete access privileges
to all files on the machine.
root suffix The parent of one or more sub suffixes. A directory tree can contain more than one root suffix.
S
SASL An authentication framework for clients as they attempt to bind to a directory. Also Simple
Authentication and Security Layer .
schema Definitions describing what types of information can be stored as entries in the directory. When
information that does not match the schema is stored in the directory, clients attempting to access
the directory may be unable to display the proper results.
schema checking Ensures that entries added or modified in the directory conform to the defined schema. Schema
checking is on by default, and users will receive an error if they try to save an entry that does
not conform to the schema.
