Defines the credential information and sends that information across the network so that a receiving server can interpret it.
When you send authentication information across the network using a token the transmission is considered message layer authentication because the data is sent with the message inside a service context.
A pure Java™ client uses Kerberos (KRB5) or basic authentication, or Generic Security Services Username Password (GSSUP), as the authentication mechanism to establish client identity.
The security token that is contained in a token-based credential is authentication mechanism-specific. The way that the token is interpreted is only known by the authentication mechanism. Therefore, each authentication mechanism has an object ID (OID) representing it. The OID and the client token are sent to the server, so that the server knows which mechanism to use when reading and validating the token. The following list contains the OIDs for each mechanism:
BasicAuth (GSSUP): oid:2.23.130.1.1.1
SWAM: No OID because it is not forwardable
