LDAP n8n INTEGRATION: AUTOMATE LDAP WITH N8N

The Create action allows you to add new entries to your LDAP directory programmatically. This is the foundation of automated user provisioning workflows, enabling you to create user accounts, groups, organizational units, or any other LDAP object type directly from your n8n workflows.

Key parameters:

• Credential to connect with: A required dropdown where you select your pre-configured LDAP account credentials to authenticate the connection to your directory server.
• DN (Distinguished Name): A required text field where you specify the full DN for the new entry you're creating. This determines exactly where in your directory tree the entry will be placed (e.g., cn=john.doe,ou=users,dc=company,dc=com).
• Attributes: A section where you define key-value pairs representing the LDAP attributes for your new entry. Click "Add Attributes" to specify properties like objectClass, sn, givenName, mail, userPassword, and any other attributes required by your directory schema.

Use cases:

• Automatically create user accounts when new employees are added to your HR system
• Provision service accounts as part of application deployment workflows
• Create group entries and organizational units as your company structure evolves
• Batch-create test users for QA environments from a spreadsheet or database

This action is particularly valuable for organizations with frequent onboarding or those managing multiple directory environments. Combined with data from HR systems, CRMs, or ticketing platforms, you can build fully automated provisioning pipelines that eliminate manual account creation entirely.

The Search action is your gateway to querying LDAP directory data. It allows you to find entries based on attribute values, retrieve user information, list group members, or perform complex directory lookups—all within your n8n workflows.

Key parameters:

• Credential to connect with: A required dropdown to select the LDAP account credentials for authentication.
• Base DN: A required text field specifying the starting point in your directory tree for the search (e.g., ou=users,dc=n8n,dc=io). This defines the search scope and significantly impacts performance on large directories.
• Search For: A dropdown menu to select the type of object you want to find, helping tailor your search to specific entry types.
• Attribute: A dropdown allowing you to specify which attribute to search against. Supports both fixed values and dynamic expressions.
• Search Text: A text field where you enter the value that the specified attribute should match.
• Return All: A toggle switch that determines whether to return all matching results. When off, results are limited by the Limit parameter.
• Limit: A number field (default: 50) specifying the maximum number of results to return when "Return All" is disabled.
• Options: An expandable section for additional LDAP search parameters like scope, size limit, or attribute selection.

Use cases:

• Look up user details before updating records in other systems
• Find all members of a specific group for notification workflows
• Search for users with specific attributes (e.g., all users in a department)
• Verify if a user exists before attempting to create or modify them

The Search action forms the backbone of most LDAP integration workflows. Whether you're building a user lookup service, synchronizing directory data to external systems, or implementing conditional logic based on user attributes, this action provides the querying capability you need.

The Update action enables you to modify existing LDAP entries by changing their attribute values. This is essential for keeping directory data synchronized with changes from other systems, implementing attribute management workflows, or bulk-updating user properties.

Key parameters:

• Credential to connect with: A required dropdown for selecting your LDAP authentication credentials.
• DN (Distinguished Name): A required text field where you specify the exact DN of the LDAP entry you want to modify. This must match an existing entry in your directory.
• Update Attributes: A section where you define the attribute modifications to apply. Add key-value pairs representing the attributes and their new values—these will overwrite existing values or add new attributes to the entry.

Use cases:

• Sync user profile changes from HR systems to Active Directory (job title, department, manager)
• Update contact information when users modify their profiles in other applications
• Manage custom attributes used for application authorization
• Bulk-update attributes across multiple users as part of organizational changes

💡 Pro tip: Combine the Search action with Update to build dynamic workflows that first find entries matching certain criteria, then update them accordingly. This pattern is powerful for scenarios like "find all users in Department X and update their manager attribute to the new department head."

The Delete action removes entries from your LDAP directory permanently. Use this action carefully, as deleted entries cannot be recovered without backup restoration. It's essential for user deprovisioning workflows, cleanup automation, and maintaining directory hygiene.

Key parameters:

• Credential to connect with: A required dropdown to select the LDAP account credentials with sufficient permissions to delete entries.
• DN (Distinguished Name): A required text field (supports expressions) where you must provide the full DN of the LDAP entry to delete. This specifies exactly which object will be removed from the directory.

Use cases:

• Automated user deprovisioning when employees leave the organization
• Clean up test accounts after QA processes complete
• Remove temporary entries created during workflow operations
• Implement retention policies that delete inactive accounts after a certain period

Important consideration: Before implementing delete workflows, ensure your LDAP credentials have appropriate permissions and that you have proper backup procedures in place. Consider implementing a "soft delete" pattern where you first disable or move accounts to a "pending deletion" OU before final removal, giving you a recovery window if needed.

The Rename action allows you to change the Distinguished Name of an existing LDAP entry, effectively moving or renaming it within your directory tree. This is crucial for organizational restructuring, user transfers between departments, or correcting naming conventions.

Key parameters:

• Credential to connect with: A required dropdown for selecting your LDAP authentication credentials with rename permissions.
• DN (Distinguished Name): A required text field where you specify the current full DN of the entry you want to rename. Supports expressions for dynamic input.
• New DN: A required text field for entering the new Distinguished Name. This includes the new common name (CN) and the organizational path (e.g., cn=nathan,ou=users,dc=n8n,dc=io).

Use cases:

• Move user accounts between organizational units when employees change departments
• Rename entries to match updated naming conventions
• Reorganize directory structure during company mergers or restructuring
• Transfer groups or resources to different parts of the directory tree

The Rename action is particularly valuable during organizational changes. When a user moves from the Sales OU to Marketing, you can automatically update their directory location, ensuring group memberships and access controls remain consistent with their new role.

The Compare action performs an attribute comparison against a specific LDAP entry, returning a boolean result indicating whether the attribute matches the specified value. This is useful for verification workflows, authentication checks, and conditional logic based on directory attributes.

Key parameters:

• Credential to connect with: A required dropdown for selecting your LDAP authentication credentials.
• DN (Distinguished Name): A required text field specifying the exact DN of the LDAP entry to compare against.
• Attribute ID: A required dropdown where you select which LDAP attribute to compare.
• Value: A text field where you enter the value to compare the selected attribute against.

Use cases:

• Verify user membership in specific groups before granting access
• Check if attribute values match expected states as part of compliance workflows
• Implement conditional routing in workflows based on user attributes
• Audit password policy compliance by comparing against known values

The Compare action is more efficient than Search when you only need to verify a specific attribute value. Instead of retrieving the entire entry and parsing attributes, Compare performs the check server-side and returns a simple true/false result, making it ideal for high-volume verification workflows. For complex data validation, consider combining LDAP with Airtable via n8n for structured data management.
