1.2. How does LDAP work ?
LDAP directory service is based on a client-server model. One or more LDAP
servers contain the data making up the LDAP directory tree or LDAP backend
database. An LDAP client connects to an LDAP server and asks it a question. The
server responds with the answer, or with a pointer to where the client can get
more information (typically, another LDAP server). No matter what LDAP server
a client connects to, it sees the same view of the directory; a name presented
to one LDAP server references the same entry it would at another LDAP server.
This is an important feature of a global directory service, like LDAP.
