Pre-Requisites:

 

Before enabling LDAPS in the SolarWinds Self-Hosted Platform, make sure your Domain Controller has a valid SSL certificate installed that includes the server’s FQDN and supports Server Authentication. LDAPS (TCP port 636) must be enabled and reachable from your SolarWinds server, and firewalls should allow secure traffic to the Domain Controller on this port.
