Configure WAS and enabling the SPNEGO TAI (deprecated)
Performing this task helps you, as web administrator, to ensure that WAS is properly configured to enable the operation of the Simple and Protected GSS-API Negotiation (SPNEGO) trust association interceptor (TAI). You need to know how to use the WAS administrative console to manage the security configuration and have the proper authority to modify the security configuration of the application server.
Deprecated feature:
In WAS v6.1, 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 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 Complete the following steps to enable the operation of the SPNEGO TAI.
Procedure
- Log on to the WAS administrative console.
- Click Security > Global security.
- Expand Web security and click Trust association.
- Under the General Properties heading, select the Enable trust association check box, then click Interceptors.
- Select the SPNEGO TAI in the list of interceptors.
- Then click Custom properties.
- Click New and then fill in the Name and Value fields.
Click OK. Repeat this step for each custom property that you want to apply to the SPNEGO TAI. See
SPNEGO TAI custom properties configuration (deprecated) for a complete list of SPNEGO TAI custom properties.
IBM recommends that you use the wsadmin.sh utility to manage the SPNEGO TAI properties. We can add, modify, and delete SPNEGO TAI properties as well as display them using wsadmin. See Add SPNEGO TAI properties using the wsadmin utility (deprecated) to add, Modify SPNEGO TAI properties using the wsadmin utility (deprecated) to modify, and Delete SPNEGO TAI properties using the wsadmin utility (deprecated) to delete SPNEGO TAI properties.
- After you finish defining your custom properties, click Save to store the updated SPNEGO TAI configuration.
- Optional: If an alias for a connecting host name is added dynamically after the application server is started, you need to configure the alias. Refer to the Use an alias host name for SPNEGO TAI or SPENGO web authentication (deprecated) topic.
Results
Your SPNEGO TAI configuration is now configured for WAS.
