Results
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.
