Migrating Sun Java Directory Server to HP-UX Directory Server White Paper

5
Terms and Conventions Used in this White Paper
Table 2: Terms and conventions
Term Definition
ACI Access Control Instruction, used to provide or restrict access to entries, attributes, or values
in the directory tree.
Attribute The label for an element of information that is stored in an LDAP entry.
Class of Service (CoS) A method of inserting virtual attributes into a set of entries.
Consumer replica A read-only replica instance that does not allow LDAP clients to perform updates. A
consumer replica is a replication end point; updates received from other replicas cannot
be further replicated to other replicas.
DSCC Directory Server Control Center, the graphical administration interface for SJDS.
dse.ldif
Text file in LDIF format where instance configuration settings are stored as the cn=config
entry and its child entries.
Extended schema Schema definitions that have been added to the directory server to extend the standard
schema.
HPDS Abbreviation used throughout this document to refer to the HP-UX Directory Server.
Hub replica A read-only replica instance that does not allow LDAP clients to perform updates. Updates
received from other replicas are in turn replicated to other hub or consumer replicas.
Index Key data (attributes of a directory server entry) stored in a quickly searchable database.
To expedite search operations, it maintains a list of entries that match various conditions.
Instance A configured directory server. Multiple instances can run on a single host, and will
appear as “ns-slapd” in a process list. Instances can serve their own data set or hold
replica data.
Instance path The file system path of the configuration, database files, log files, and instance-specific
scripts that are used by a directory server instance. On SJDS, the instance path is one
directory, under which all the above are found. On HPDS, the scripts, configuration, and
data are found under three different paths.
LDIF LDAP Interchange Format, a file format used to represent LDAP data in plain text form.
Master replica A replica instance that allows LDAP clients to perform update operations, which are in turn
replicated to other master, hub, or consumer replicas.
Memory arenas Memory pools automatically allocated by the memory manager to improve performance of
threaded applications.
Object class Describes the type of LDAP entry, and controls which attributes may or must appear in the
entry.
Password policy A set of rules that defines the usage and restrictions of the passwords assigned to entries in
the directory tree.
Replica instance A directory instance that manages replicated data and sends or receives replication
updates.
Replication topology A collection of replicated instances, usually found on multiple hosts distributed across an
organization.
SASL Simply Authentication and Security Layer, a framework for providing pluggable
authentication mechanisms.
Schema A set of rules that govern the types of information that may exist in directory server entries.
HPDS installs a set of commonly used standard schema.
Self-signed certificate A certificate that is signed by itself. Normally, a separate certificate, called an issuer or
certificate authority certificate, will be used to sign a certificate.
SJDS Abbreviation used throughout this document to refer to the Sun Java System Directory
Server.
