Performing this task helps you, as web administrator, to ensure that WebSphere® Application Server is configured to enable the operation of the Simple and Protected GSS-API Negotiation mechanism (SPNEGO) trust association interceptor (TAI) with the required Java virtual machine (JVM) property and with the appropriate filtering of HTTP requests.
In WebSphere Application Server Version 6.1, a trust association interceptor (TAI) that uses the Simple and Protected GSS-API Negotiation Mechanism (SPNEGO) to securely negotiate and authenticate HTTP requests for secured resources was introduced. In WebSphere Application Server 7.0, this function is now deprecated. SPNEGO web authentication has taken its place to provide dynamic reload of the SPNEGO filters and to enable fallback to the application login method.
depfeatThe default behavior of the SPNEGO TAI is to not intercept HTTP requests. This default behavior ensures that the SPNEGO TAI can be installed into an existing cell, configured for a single application server and not change any other application servers in the cell. Other WebSphere Application Servers can run exactly as before within a given configuration.
