/**
  * Required callbacks:
  * - RealmCallback
  *    handle can provide domain info for authentication, optional
  * - NameCallback
  *    handler must enter username to use for authentication
  * - PasswordCallback
  *    handler must enter password for username to use for authentication
  *
  * Environment properties that affect behavior of implementation:
  *
  * javax.security.sasl.qop
  *    String, quality of protection; only "auth" is accepted, default "auth"
  *
  * com.sun.security.sasl.ntlm.version
  *    String, name a specific version to use; can be:
  *      LM/NTLM: Original NTLM v1
  *      LM: Original NTLM v1, LM only
  *      NTLM: Original NTLM v1, NTLM only
  *      NTLM2: NTLM v1 with Client Challenge
  *      LMv2/NTLMv2: NTLM v2
  *      LMv2: NTLM v2, LM only
  *      NTLMv2: NTLM v2, NTLM only
  *    If not specified, use system property "ntlm.version". If
  *    still not specified, use default value "LMv2/NTLMv2".
  *
  * com.sun.security.sasl.ntlm.random
  *    java.util.Random, the nonce source to be used in NTLM v2 or NTLM v1 with
  *    Client Challenge. Default null, an internal java.util.Random object
  *    will be used
  *
  * Negotiated Properties:
  *
  * javax.security.sasl.qop
  *    Always "auth"
  *
  * com.sun.security.sasl.html.domain
  *    The domain for the user, provided by the server
