This creates a connection to the directory server and authenticates the user through LDAP using his DN and password. To authenticate the user, Joe Simms, we need to create a new InitialDirContext object. This will authenticate Joe through LDAP using his DN and password, as defined in the file. To run it against the LDAP server, we'll need to add our code to a method in our unit test class. Next, we'll discuss the example code that will authenticate the user. When doing so, the server will load the entry for the user Joe Simms. This is so the ApacheDS server can load LDIF formatted directory entries from this file when we run our code example. Lastly, we'll also need to add users.ldif to the classpath. We can see which values to give them from the full code example, which we will explore later. As this library is not compatible with JUnit 5 yet, we need to use JUnit 4.Īdditionally, we need to include Java annotations above our unit test class declaration to configure the server. To use the embedded ApacheDS server in this class, we must declare that it extends AbstractLdapTestUnit from the ApacheDS library. Next, we need to create a unit test class using JUnit 4. Therefore, we can use JNDI to access an LDAP directory service without needing to use protocol-specific APIs. In JNDI, children of directory entries are represented as subcontexts of their parent context.Ī key benefit of the JNDI API is that it's independent of any underlying service provider implementation, for example, LDAP. This enables entries to be linked hierarchically. This is because a directory service is merely a specialized type of naming service that enables each named entry to have a list of attributes associated with it.īesides attributes, each directory entry may have one or more children. We can access directory services, like LDAP, by using the naming service interface of JNDI. The name given to each of these local or network-accessible resources is configured on the server hosting the naming service. Naming services underly this capability because they provide single-point access to services, data, or objects by name in a hierarchical namespace. This being, both locally and over a network. Its fundamental purpose is to provide a way for applications to access components and resources. JNDI provides a standard API for applications to discover and access naming and directory services.
