LDAP Overview
LDAP Server provides a centralized phonebook management. With the LDAP phonebook, you can quickly launch calls without wasting time finding a contact’s number and subsequently entering it on your phone.
LDAP stands for Lightweight Directory Access Protocol which is a client-server protocol for accessing a directory service.
What kind of information can be stored in the LDAP directory?
The LDAP information model is based on entries.
An entry is a collection of attributes that has a globally-unique Distinguished Name (DN).
The DN is used to refer to the entry clearly. Each of the entry's attributes has a type and one or more values. The types are typically mnemonic strings, like "cn" for common name, or "mail" for email address.
The syntax of values depends on the attribute type. For example, a cn attribute might contain the value "test". A mail attribute might contain the value "test@example.com".
