Jboss Server 5.1.
Our users are occasionally getting 401 error code from the server. This seems to correspond with the following errors in the jboss error log
2011-07-25 10:59:06,091 WARN [org.jboss.security.negotiation.spnego.SPNEGOLoginModule] (http-172.17.187.200-80-4) Authentication was performed despite already being authenticated!

We're not exactly sure, because there is no identifying information in this message, but these messages seem to coincide with the user hitting the unauthorized.html page.
We have a custom "unauthorized" page which is invoked properly much of the time. From web.xml
<security-constraint>
<display-name>Allow access to Unauthorized error page</display-name>
<web-resource-collection>
<web-resource-name>HTML</web-resource-name>
<url-pattern>*.html</url-pattern>
</web-resource-collection>
</security-constraint>
<error-page>
<error-code>401</error-code>
<location>/unauthorized.html</location>
</error-page>
Please let me know if you need any more information. I didn't set this up originally, but I'm trying to understand how it works.
