 * CWE: 90 LDAP Injection
 * BadSource: PropertiesFile Read data from a .properties file (in property named data)
 * GoodSource: A hardcoded string
 * Sinks:
 *    BadSink : data concatenated into LDAP search, which could result in LDAP Injection
 * Flow Variant: 31 Data flow: make a copy of data within the same method
