Introduction
This article is focused on providing clear, simple, actionable guidance for preventing LDAP Injection flaws in your applications. LDAP Injection attacks are somewhat common, and this is due to two factors:
- the lack of safer, parameterized LDAP query interfaces, and
- the widespread use of LDAP to authenticate users to systems.

Additional Defenses
Beyond adopting one of the three primary defenses, we also recommend adopting all of these additional defenses in order to provide defense in depth. These additional defenses are:
- Least Privilege
- White List Input Validation
Least Privilege
To minimize the potential damage of a successful LDAP injection attack, you should minimize the privileges assigned to the LDAP binding account in your environment.
TBA
White List Input Validation
Input validation can be used to detect unauthorized input before it is passed to the SQL query. For more information please see the Input Validation Cheat Sheet.
