If an independent AD server is used, enable LDAPS on the Active AD server > verify the connection between LDAPS and the active AD server.
If the AD servers work in active/standby mode, enable LDAPS on the active AD server > verify the connection between LDAPS and the active AD server > enable LDAPS on the standby AD server > verify the connection between LDAPS and the standby AD server.
