Configuring the client browser to use SPNEGO

You can configure your browser to utilize the Simple and Protected GSS-API Negotiation (SPNEGO) mechanism.

Before you begin

You need to know how to display and set options in a browser (such as Firefox). You must have a browser installed that supports SPNEGO authentication.

About this task

Complete the following steps to ensure that your Firefox browser is enabled to perform SPNEGO authentication.
  1. At the desktop, log in to the windows active directory domain.
  2. Activate Firefox.
  3. At the address field, type about:config.
  4. In the Filter, type network.n
  5. Double click on network.negotiate-auth.trusted-uris. This preference lists the sites that are permitted to engage in SPNEGO Authentication with the browser. Enter a comma-delimited list of trusted domains or URLs.
    Note: You must set the value for network.negotiate-auth.trusted-uris.
  6. If the deployed SPNEGO solution is using the advanced Kerberos feature of Credential Delegation double click on network.negotiate-auth.delegation-uris. This preference lists the sites for which the browser may delegate user authorization to the server. Enter a comma-delimited list of trusted domains or URLs.
  7. Click OK. The configuration appears as updated.
  8. Restart your Firefox browser to activate this configuration.


Your Internet browser is properly configured for SPNEGO authentication. You can use applications that are deployed in WebSphere® Application Server that use secured resources without being repeatedly requested for a user ID and password.

Note: If you are prompted multiple times for a user ID and password, make sure that you enabled SPNEGO support on your client browser per the previous instructions. You must also make sure that the Allow fall back to application authentication mechanism support option is enabled on the WebSphere Application Server server side.
