"Authentication denied: Boot identity not valid; "

This post is for WEBLOGIC Server Issue.

If you hit with this exception while launching your weblogic server the below are the fix you can try.

1. Launch the Admin console.
2. Click on the domain.
3. Click on the general tab.
4. Click on the Server start
5. In the Arguments property serach for the proxy entries and keep the values for those proxy entries as empty values.

Because the server is trying with the proxy and if there is some problem with the proxy it throws the Boot Identity not valid error.

Remove the proxy information from the arguments. Make the -Dhttp.proxySet=false as false. by default it will be "true".

Then restart the domain.

Hope your domain will come up.

If you still have problem, plz detail your exception.
