LDAP Amplication Denial Of Service

This proof of concept is an LDAP Distributed Reflective Denial of Service/Bandwidth Amplification Attack, similar to DNS and NTP amplification attacks where the target of the DoS is spoofed as the source IP in a request to the reflectors(In this case, LDAP servers). The reflectors then respond to the spoofed target IP with a bigger answer than the original question, resulting in the target experiencing what appears to be a distributed denial of service attack, even though there may only be one true source. suffers from a denial of service vulnerability.
