This example is useful when you need a quick LDAP verification pass before deeper Active Directory troubleshooting.

It comes from the source example at Examples/Example.06-TestLDAPPorts.ps1.

When to use this pattern

• You need to confirm LDAP connectivity to domain controllers.
• You want to validate certificate-backed LDAP communication.
• You are checking whether a directory issue is network, certificate, or service related.

Example

Import-Module .\ADEssentials.psd1 -Force

Test-LDAP -IncludeDomainControllers 'dc01.corp.example.com' -Identity "krbtgt" -Verbose | Format-List *
Test-LDAP -ComputerName 'corp.example.com' -VerifyCertificate -Verbose | Format-Table
Test-LDAP -VerifyCertificate -Verbose -IncludeDomains 'corp.example.com' | Format-Table

What this demonstrates

• testing specific domain controllers directly
• validating LDAP over certificate-backed channels
• comparing narrow and broad validation runs from the same command family
