ldaphost389

ldaphost389 is a hostname commonly used to refer to an LDAP directory server in IT environments. The inclusion of the number 389 is often a nod to the default LDAP port (389), and the name appears in documentation, example configurations, and deployment scripts as a representative server address for directory services. In practice, ldaphost389 may resolve to a physical or virtual machine running LDAP software such as OpenLDAP, 389 Directory Server, or a feature-compatible instance of Microsoft Active Directory.

In typical deployments, ldaphost389 is registered in the local DNS system or listed in a hosts file to provide a stable network name for clients and services that need to query the directory. LDAP clients connect to this host over the LDAP protocol, usually using the URI ldap://ldaphost389 or, for encrypted connections, StartTLS on port 389 or LDAPS on port 636. The server hosts a directory information base and responds to directory lookups, binds, and directory modification operations, subject to access control policies.

Configuration commonly involves specifying a base distinguished name (base DN), a bind DN and credentials for authentication, and appropriate search scopes for directory queries. For example, a client might connect with an LDAP URI targeting ldaphost389, perform a base search for a domain component (dc=example,dc=com), and authenticate with a service account. Security considerations include enabling encryption, controlling bind privileges, auditing access, and limiting exposure to only trusted networks.

While ldaphost389 serves as a practical placeholder in examples and tests, real deployments use concrete hostnames that reflect organizational naming conventions and DNS properites. The exact role and capabilities of the server depend on the environment and the LDAP software in use.
