GssApiAuthenticator

protected GssApiAuthenticator(DseGssApiAuthProviderBase.GssApiOptions options,
                              EndPoint endPoint,

Method Detail

getMechanism

@NonNull
protected ByteBuffer getMechanism()

Description copied from class: BaseDseAuthenticator

Return a byte buffer containing the required SASL mechanism.

This should be one of:

• PLAIN
• GSSAPI

This must be either a read-only buffer, or a new instance every time.

Specified by:

getMechanism in class BaseDseAuthenticator

getInitialServerChallenge

@NonNull
protected ByteBuffer getInitialServerChallenge()

Description copied from class: BaseDseAuthenticator

Return a byte buffer containing the expected successful server challenge.

This should be one of:

• PLAIN-START
• GSSAPI-START

This must be either a read-only buffer, or a new instance every time.

Specified by:

getInitialServerChallenge in class BaseDseAuthenticator

evaluateChallengeSync

@Nullable
public ByteBuffer evaluateChallengeSync(@Nullable
                                        ByteBuffer challenge)

Description copied from interface: SyncAuthenticator

Evaluate a challenge received from the server.

SyncAuthenticator.evaluateChallenge(ByteBuffer) calls this and wraps the result in an immediately completed future.

Parameters:

challenge - the server's SASL challenge; may be null.

Returns:

The updated SASL token (which may be null to indicate the client requires no further action). Note that, if the returned byte buffer is writable, the driver will clear its contents immediately after use (to avoid keeping sensitive information in memory); do not reuse the same buffer across multiple invocations. Alternatively, if the contents are not sensitive, you can make the buffer read-only and safely reuse it.
