Okta LDAP Port Test.ps1

<#
    Helper script I ran once or twice trying to narrow down issues with our Okta LDAP service.
    
    Output should be a log file with a nicely formatted timestamp that gives a better idea as
    to when (and with which Okta datacenter IPs) your ldap connections might be struggling.
    Tests connectivity every 30 seconds until stopped.

    ! Modify the domain.ldap.okta.com domain below to match your tenant.

filter timestamp {"$('[{0:MM/dd/yyyy} {0:HH:mm:ss}]' -f (Get-Date)) $_"}

    $resolvedips = Resolve-DnsName domain.ldap.okta.com
