attribute are extended to deﬁne a new schema. The extended schema

ﬁle used to authenticate and authorize users logging in to the B051-

LDAP Data Structure

An LDAP directory stores information in a tree structure known

as the Directory Information Tree (DIT). The nodes in the tree are

directory entries, and each entry contains information in attribute-

value form. An example of the LDAP directory tree for the B051-000

is shown in the ﬁgure, below:

The LDAP Data Interchange Format (LDIF) is used to represent

LDAP entries in a simple text format (please refer to RFC 2849). The

ﬁgure below illustrates an LDIF ﬁle that creates the DIT for the B051-

000 directory tree (shown in the ﬁgure, above).

The following ﬁgure illustrates an LDIF ﬁle that deﬁnes the

OpenLDAP group for the B051-000.
