Authenticator (Apache TinkerPop 3.7.2 API)

All Known Implementing Classes:

AllowAllAuthenticator, Krb5Authenticator, SimpleAuthenticator
```
public interface Authenticator
```
Provides methods related to authentication of a request. Implementations should provide a SASL based authentication method, but a handler can choose to use the authenticate(Map) method directly if required for protocols that don't easily support SASL.

Modifier and Type Interface Description

static interface Authenticator.SaslNegotiator
Performs the actual SASL negotiation for a single authentication attempt.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`AuthenticatedUser`	`authenticate(Map<String,String> credentials)`	A "standard" authentication implementation that can be used more generically without SASL support.
`Authenticator.SaslNegotiator`	`newSaslNegotiator(InetAddress remoteAddress)`	Provide a SASL handler to perform authentication for an single connection.
`boolean`	`requireAuthentication()`	Whether or not the authenticator requires explicit login.
`void`	`setup(Map<String,Object> config)`	Setup is called once upon system startup to initialize the `Authenticator`.

- Method Detail
  - requireAuthentication
```
boolean requireAuthentication()
```
    Whether or not the authenticator requires explicit login. If false will instantiate user with AuthenticatedUser.ANONYMOUS_USER.
  - setup
```
void setup(Map<String,Object> config)
```
    Setup is called once upon system startup to initialize the Authenticator.
  - newSaslNegotiator
```
Authenticator.SaslNegotiator newSaslNegotiator(InetAddress remoteAddress)
```
    Provide a SASL handler to perform authentication for an single connection. SASL is a stateful protocol, so a new instance must be used for each authentication attempt.
    
    Parameters:
    
    remoteAddress - the IP address of the client to authenticate to authenticate or null if an internal client (one not connected over the remote transport).
  - authenticate
```
AuthenticatedUser authenticate(Map<String,String> credentials)
                        throws AuthenticationException
```
    A "standard" authentication implementation that can be used more generically without SASL support. This implementation is used when a particular Channelizer doesn't support SASL directly (like basic HTTP authentication).
    
    Throws:
    
    AuthenticationException
