Examples of javax.management.remote.message.SASLMessage

javax.management.remote.message.SASLMessage
A challenge or response exchanged between client and server during SASL authentication. This message encapsulates either a challenge or a response generated by the SASL mechanism during the SASL authentication exchanges taking place between the client and the server.

The challenges/responses (blobs) are generated by the SASL mechanism:
- The challenges are generated by the server side SASL mechanisms.
- The responses are generated by the client side SASL mechanisms in response to the server challenges.
The status attribute takes one of the two values:
- CONTINUE: used by either a client or server to indicate that they require more interaction with the other peer in order to complete the authentication exchange.
- COMPLETE: used by a server to indicate that the exchange is complete and successful.
At any time during the SASL handshake, if the server encounters a problem it can notify the client by sending an {@link HandshakeErrorMessage indication}as to why the operation failed.
At any time during the SASL handshake, if the client encounters a problem or wants to abort the authentication exchange it can notify the server by sending an {@link HandshakeErrorMessage indication} as to why the operationfailed or is aborted.
The profile name in this profile message is built by concatenating the prefix "SASL/" with the SASL mechanism name provided by the IANA SASL registry.
Examples of SASL profile names are:
- SASL/GSSAPI
- SASL/EXTERNAL
- SASL/CRAM-MD5
- SASL/ANONYMOUS
- SASL/OTP
- SASL/PLAIN
- SASL/DIGEST-MD5
