Invoking methods on the {@code SaslClient} instance * process challenges and create responses according to the SASL * mechanism implemented by the {@code SaslClient}. * As the authentication proceeds, the instance * encapsulates the state of a SASL client's authentication exchange. *<p> * Here's an example of how an LDAP library might use a {@code SaslClient}. * It first gets an instance of a {@code SaslClient}: *<blockquote><pre>{@code * SaslClient sc = Sasl.createSaslClient(mechanisms, * authorizationId, protocol, serverName, props, callbackHandler); *}</pre></blockquote> * It can then proceed to use the client for authentication. * For example, an LDAP library might use the client as follows: *<blockquote><pre>{@code * // Get initial response and send to server * byte[] response = (sc.hasInitialResponse() ? sc.evaluateChallenge(new byte[0]) : * null); * LdapResult res = ldap.sendBindRequest(dn, sc.getName(), response); * while (!sc.isComplete() && * (res.status == SASL_BIND_IN_PROGRESS || res.status == SUCCESS)) { * response = sc.evaluateChallenge(res.getBytes()); * if (res.status == SUCCESS) { * // we're done; don't expect to send another BIND * if (response != null) { * throw new SaslException( * "Protocol error: attempting to send response after completion"); * } * break; * } * res = ldap.sendBindRequest(dn, sc.getName(), response); * } * if (sc.isComplete() && res.status == SUCCESS) { * String qop = (String) sc.getNegotiatedProperty(Sasl.QOP); * if (qop != null * && (qop.equalsIgnoreCase("auth-int") * || qop.equalsIgnoreCase("auth-conf"))) { * * // Use SaslClient.wrap() and SaslClient.unwrap() for future * // communication with server * ldap.in = new SecureInputStream(sc, ldap.in); * ldap.out = new SecureOutputStream(sc, ldap.out); * } * } *}</pre></blockquote> * * If the mechanism has an initial response, the library invokes * {@code evaluateChallenge()} with an empty * challenge and to get initial response. * Protocols such as IMAP4, which do not include an initial response with * their first authentication command to the server, initiates the * authentication without first calling {@code hasInitialResponse()} * or {@code evaluateChallenge()}. * When the server responds to the command, it sends an initial challenge. * For a SASL mechanism in which the client sends data first, the server should * have issued a challenge with no data.
