SPNEGO TAI configuration requirements (deprecated)


The configuration used by the SPNEGO TAI on each selected appserver is governed by various system requirements.

Deprecated feature:

In WAS Version 6.1, a TAI that uses the SPNEGO to securely negotiate and authenticate HTTP requests for secured resources was introduced. In WAS 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. depfeat

The following list of configuration requirements highlights those attributes, properties, qualities, restrictions, exclusions, inclusions, and dependencies that we need to be aware of when planning a WAS configuration that incorporates the use of the SPNEGO TAI.
