LDAP

The commands of the "LDAP" theme allow your 4D application to connect to a company directory server such as MS Active Directory using the LDAP protocol. You can access the server data and query it.

Note: LDAP or Lightweight Directory Access Protocol is an open standard for accessing and maintaining distributed information services. For more information, please refer to the Wikipedia page on LDAP or the OpenLDAP Software main page.

LDAP commands allow you to:

use the Windows session login and password to grant access to your 4D application (if using MS Active directory) so that the end user only needs to remember a single password,
query the corporate directory to retrieve user information such as full name, email, phone number, office building, groups the person belongs to, etc.

In 4D, an LDAP connection is opened using LDAP LOGIN. It is then bound to the current 4D process and must be closed using LDAP LOGOUT, or when the process terminates its execution.
