 * CWE: 90 LDAP Injection
 * BadSource: environment Read input from an environment variable
 * GoodSource: Use a fixed string
 * Sinks:
 *    BadSink : data concatenated into LDAP search, which could result in LDAP Injection
 * Flow Variant: 81 Data flow: data passed in a parameter to an virtual method called via a reference
