Integrated Windows Authentication (IWA) refers to a set of authentication protocols, NTLM, Kerberos, and SPNEGO, that are used to provide transport-level security. You can configure IBM® Integration Bus to provide an IWA-secured service on an integration node running on any operating system, and to consume an IWA-secured service on an integration node running on Windows, when you are using the HTTP and SOAP nodes.
You can use IWA with the HTTPInput and SOAPInput nodes to provide a service. For more information on configuring IBM Integration Bus to provide an IWA-secured service, see Authenticating incoming requests with IWA on Windows and Authenticating incoming requests with IWA on Linux or UNIX.
To consume an IWA-secured service, use the HTTPRequest and SOAPRequest nodes. For more information on configuring this scenario, see Providing credentials for outbound requests by using IWA. You can consume an IWA-secured service only if IBM Integration Bus is running on Windows.
You can also use IWA when using Microsoft SQL Server to record and replay data.
