The Complete Course of LDAP 2025

Learn how LDAP follows a client-server model by connecting a client to an LDAP directory, performing authentication and a search for a specific printer, and returning the printer address.

Explore directory data, including contact details and job information, and why read-heavy, attribute-value data fits directories while large objects go to the file system.

Explore the directory information tree (DIT) and its hierarchical structure using root and sub suffixes, aligning suffix naming with DNS to support replication, access controls, and simplified navigation.

Explore the LDAP data model, including information, naming, functional, and security models, and learn how entries, attributes, types, and matching rules define directory data.

learn how ldif represents directory data for exporting and importing from the directory server, using dn lines, ascii text, and attribute values organized with object class values first.

Learn how the ldap naming model structures data with an inverted tree, uses distinguished names and relative distinguished names to uniquely identify entries, and supports multivalued rdn and aliases.

Learn LDAP installation on Ubuntu and CentOS, updating packages, configuring hostname and permanent IP via Netplan (Ubuntu) or GNMT (CentOS), then install OpenLDAP and manage slapd (start, enable) with systemctl.

Install ldap on centos, update repositories, set the permanent ip and hostname, install ldap packages, enable and verify the service.

Configure LDAP server with dpkg reconfigure, set example.com as DNS and organization, purge and move databases, and verify with ldap search while preparing to create entries like people and groups.

Create and manage LDAP users and groups using an ld file and ldapadd, configure organizational units, and validate with ldapsearch in a practical directory services workflow.

Explore the ldap functional model, detailing interrogation, update, and authentication and control operations used to manage directory data. Learn how ldap version 3 enables extended operations to add new capabilities.

Explore LDAP interrogation operations, including search and compare, and learn how search parameters—base, scope, deref aliases, size and time limits, filter, and attributes—determine entry retrieval and attribute values.

Learn the ldap functional model and the four atomic update operations - add, delete, rename, and modify - and the conditions for safe, all-or-nothing directory entry changes under access control.

Learn the LDAP functional module, covering authentication and control operations with bind and unbind, and abandon. Understand bind methods, SASL, Kerberos, TLS, and how identity, credentials, and certificates drive access.

Master ldap add and delete operations by binding with credentials, creating a formatted entry file to add users or groups, and deleting entries with ldap delete and Python examples.

Learn how the ldap modify operation updates existing entries and supports add, delete, rename, and replace actions. The lecture demonstrates end-to-end commands with ldapmodify, ldapadd, ldapsearch, and a Python example.

Learn how to perform an LDAP compare operation using bind, authentication options, and attribute value checks, with a practical example comparing login shell values such as /bin/bash.

Learn how to perform ldap bind operations in Python, including simple bind, anonymous bind, unauthenticated simple bind, and sasl bind, then unbind and proceed to ldap search or other operations.

Explore the LDAP search operation using the ldapsearch tool, covering authentication options, base dn, scope (base, sub, children), dereferencing, and printing only attributes with examples.

Explain how LDAP filters form boolean expressions from attribute value assertions, cover equality, substring, approximate, ordering comparisons, presence and extensible matching, and negation with and/or grouping.

Explore the LDAP security model, including authentication, access control, and privilege grants during a session, with encryption via TLS and mutual X509 certificate authentication.

Learn to set up SSL/TLS for LDAP by generating certificates with OpenSSL, creating a CSR and server key, copying files, and updating LDAP configuration to enable ldaps on port 636.

Explore LDAP security best practices, including using an enterprise password manager, protecting passwords with SSL, hashing and salting passwords, input validation, LDAP injection mitigation, ACLs, monitoring, and provisioning and de-provisioning.

Explore LDAP schema rules that define what can be stored, enforce mandatory attributes, and use attributes, syntaxes, object classes, and matching rules.

Learn how LDAP uses object identifiers (OIDs) to uniquely identify schema elements. Use registered OID prefixes and a base ID per organization, then extend with branches for classes and attributes.

Explore OpenLDAP configuration files, including cn=config, olc settings, and backend databases, and learn how schema, modules, access controls, and indices shape ldap server behavior.

Configure and test an LDAP client by setting host file entries, installing LDAP utilities, and adding a user to enable LDAP login.

Learn how to integrate your web application with LDAP for authentication by using PHP on an Apache server, installing the LDAP module, and performing LDAP connect and bind.

Install the ldap user interface with php ldap admin, configure server name, host, and base, then create groups and users in the ldap server gui.

Install ldap directory services on windows server, promote to domain controller for example.com, and configure active directory lightweight directory services to manage users and groups via port 50000.

Learn to install an identity management system with LDAP on CentOS, configure users and groups, manage access and authorization, and explore policies and authentication methods.

Learn to administer an OpenLDAP server using the online configuration (OLC), explore the configuration tree rooted at config, and query schemas, modules, backends, and operational attributes with ldap search.

Learn to back up and restore an LDAP directory by creating a backup script, automating with cron, and restoring data on a remote server using LDAP utilities.

Learn how to enable and use ldap monitoring with the monitor backend, create a monitor user, configure a monitor database, and query uptime, connections, listeners, logs, statistics, and bytes.

Learn ldap troubleshooting techniques by using the slab test tool, verify slapd ports 389/636, perform ldap searches, audit acl configurations, verify ldap.conf, tls certificates, and enable debugging for issue resolution.

Tune LDAP directory performance by optimizing memory, disk, network topology, and layout, and apply smart indexing practices with equality and substring indexes.

Learn performance testing of an ldap server using the elb tool, including installing go, configuring concurrent requests, and running bind, add, search, and delete benchmarks on ldap localhost.

Explore ldap replication and the evolution from master/slave to provider and consumer topologies, including Syncrepl, ldap sync, Delta Syncrepl, and both pull and push synchronization.

Configure ldap replication by setting up a consumer, initializing slapd, and establishing a replicator bind with a provider, then verify that users replicate from provider to consumer.

Set up the ldap replication provider by creating a replication user, enabling the syncprov module, and configuring the syncprov overlay.

Explore cloud ldap and openldap future trends, including migration benefits, security, otp, mfa, load balancing, and multivalued attributes that shape modern directory services.

Review the LDAP directory services topics from history and standards to architecture and models, operations, filters, search, security, schema design, integration, administration tools, and advanced topics.
