Programming client authentication for WebSphere eXtreme Scale Client for .NET

To complete authentication, your .NET application must implement the following interfaces:

• ICredential: A Credential represents a client credential, such as a user ID and password pair.
• ICredentialGenerator: A CredentialGenerator represents a credential factory to generate the credential.

When a .NET client application connects to a server that requires authentication, the client is required to provide a client credential. A client credential is represented by the ICredential interface. A client credential can be a user name and password pair, a Kerberos ticket, a client certificate, or data in any format that the client and server agree upon. This interface explicitly defines the equals(Object) and hashCode methods. These two methods are important because the authenticated Subject objects are cached by using the Credential object as the key on the server side. You can also generate a credential with the ICredentialGenerator interface. This interface is useful when the credential can expire. A new credential is generated whenever the Credential property is obtained.

You can also use the provided CredentialGenerator plug-in to create a credential that is based on the credentialGeneratorProps= setting in the Client.Net.Properties file. The additional settings that define the credential plug-in are credentialGeneratorAssembly and credentialGeneratorClass.
