Schemas provide DEFINITIONS of the different OBJECT classes and attribute TYPES that OpenLDAP should support. Using these, OpenLDAP can determine what entries it is allowed to STORE, whether any given entry is valid, and how entries should OPTIMALLY be stored.

The moduleload DIRECTIVE INSTRUCTS OpenLDAP to LOAD a PARTICULAR MODULE.

The moduleload directive instructs OpenLDAP to load a particular module.

HDB is the NEW generation STORAGE mechanism for OpenLDAP. Like its predecessor, the BDB backend, HDB uses the Oracle BerkeleyDB database for storage, but HDB stores entries hierarchically, a perfect FIT for LDAP’s tree structure. The old BDB backend is still supported, and you can USE it by specifying bdb instead of hdb in the database DIRECTIVE.

JNDI has CLASSES provided by SUN that will help UR appln interact with and LDAP server. JNDI appln work similarly to JDBC applns once and be free to use ‘drivers’ from DIFFERENT VENDORS. SUN provides the “driver” that will help interact with the LDAP server. Sun also provides “drivers” for other naming services (like CORBA).

• -new: generate new request
• -x509: certificate display and signing utility
• -nodes: STORES private key without protecting it with a passphrase
• -out *.pem: stores certificate request in a FILE *.pem
• -keyout *key.pem: stores private key in a file *key.pem
• days: certificate activation days

SSL (Secure Sockets LAYER) certificates are an integral part of website SECURITY. When you VISIT a website with SSL the site’s SSL certificate ENABLES you to encrypt the data you send, such as credit card information, names or addresses so it can’t be accessed by hackers.
