 o Uses DIT for KeyStore
   - special schema elements added to apache schema to specifically handle the
     server keys and certificates which are assigned to the administrative user
   - special KeyStore implementation used
 o Generates key on first start to automatically enable StartTLS with zero conf
 o Uses BouncyCastle to generate self signed certificate on first start
 o LDAPS feature modified to use same DIT based KeyStore and the same self
   signed certificate and RSA keys generated or replaced by administrator
