Why is ldap called lightweight

The technology related to replication is easily configured and built-in. LDAP permits secured delegate read and modification authority based on needs using Microsoft Access control lists. No security checks are performed at the user application level. This is all done directly through the LDAP directory. LDAP does not define how programs work on the client server side, but does define the language used by client programs to talk to servers.

LDAP servers range from small servers for workgroups to large organizational and public servers. LDAP directory servers stores data hierarchically. The central concept of LDAP is the information model, which deals with the kind of information stored in directories and the structuring of information.

The information model revolves around an entry, which is a collection of attributes with type and value. Entries are organized in a tree-like structure called the directory information tree. The entries are composed around real world concepts, organization, people and objects. Attribute types are associated with syntax defining allowed information. A single attribute can enclose multiple values within it.

The distinguished names in LDAP are read from bottom to top. LDAP servers store a hierarchical directory of information. In plain and simple terms, its a database whereby it has all the details of all of organizations, individuals, and other resources such as files and devices in a network, whether on the Internet or on corporate intranetand whether or not you know the domain name, IP address, or geographic whereabouts. An LDAP directory can be distributed among many servers on a network, then replicated and synchronized regularly.

Its a not a relational database. Outlook and other email programs uses LDAP to search for a recipient in an organization. LDAP does not provide the deployment, It provide read only mechanism. So I think that it is so called lightweight. This is correct and we have one more reason that in LDAP we have one concept called updated thread pooling i. Microsoft Exchange Server stores its directory information in an X. Microsoft Outlook Express was a simple LDAP client that could be used to access personal information about recipients in an Exchange organization.

Outlook Express was discontinued on October Directory services that are not fully X. Objects within an LDAP directory are identified by their distinguished names, the standard namespace for X. For example, if Active Directory is installed on the server Server7.
