/**
 * Performs SASL authentication as a server.
 *<p>
 * A server such an LDAP server gets an instance of this
 * class in order to perform authentication defined by a specific SASL
 * mechanism. Invoking methods on the {@code SaslServer} instance
 * generates challenges according to the SASL
 * mechanism implemented by the {@code SaslServer}.
 * As the authentication proceeds, the instance
 * encapsulates the state of a SASL server's authentication exchange.
 *<p>
 * Here's an example of how an LDAP server might use a {@code SaslServer}.
 * It first gets an instance of a {@code SaslServer} for the SASL mechanism
 * requested by the client:
 *<blockquote><pre>
 * SaslServer ss = Sasl.createSaslServer(mechanism,
 *     "ldap", myFQDN, props, callbackHandler);
 *</pre></blockquote>
 * It can then proceed to use the server for authentication.
 * For example, suppose the LDAP server received an LDAP BIND request
 * containing the name of the SASL mechanism and an (optional) initial
 * response. It then might use the server as follows:
 *<blockquote><pre>{@code
 * while (!ss.isComplete()) {
 *     try {
 *         byte[] challenge = ss.evaluateResponse(response);
 *         if (ss.isComplete()) {
 *             status = ldap.sendBindResponse(mechanism, challenge, SUCCESS);
 *         } else {
 *             status = ldap.sendBindResponse(mechanism, challenge,
                   SASL_BIND_IN_PROGRESS);
 *             response = ldap.readBindRequest();
 *         }
 *     } catch (SaslException e) {
 *          status = ldap.sendErrorResponse(e);
 *          break;
 *     }
 * }
 * if (ss.isComplete() && status == SUCCESS) {
 *    String qop = (String) sc.getNegotiatedProperty(Sasl.QOP);
 *    if (qop != null
 *        && (qop.equalsIgnoreCase("auth-int")
 *            || qop.equalsIgnoreCase("auth-conf"))) {
 *
 *      // Use SaslServer.wrap() and SaslServer.unwrap() for future
 *      // communication with client
 *      ldap.in = new SecureInputStream(ss, ldap.in);
 *      ldap.out = new SecureOutputStream(ss, ldap.out);
 *    }
 * }
 *}</pre></blockquote>
