LDAP Injection Authentication Bypass


Lightweight Directory Access Protocol (LDAP) is used by web applications to access and maintain directory information services. One of the most common uses for LDAP is to provide a Single - Sign - On(SSO) service that will allow clients to authenticate with a web site without any interaction(assuming their credentials have been validated by the SSO provider). LDAP injection occurs when untrusted data is used by the web application to query the LDAP directory without prior sanitisation.
