request requires HTTP authentication

[Bhaarat Sharma]

All of a sudden I am getting this when clicking a link that was previously
working on my site
HTTP Status 401 -
------------------------------

*type* Status report

*message* **

*description* *This request requires HTTP authentication ().*


link is in the navigation and is pretty simple. here is the struts.xml for
this


  <package name="DebtsOwedtoPHAs" namespace="/DebtsOwedtoPHAs"
extends="struts-default">

      <default-interceptor-ref name="paramsPrepareParamsStack"/>

      <action name="test">

        <result>/reports/debtsowed/debtnoticepage.jsp</result>

     </action>

   </package>


here is the link:

<td class="nav">

            <a href="/eiv/DebtsOwedtoPHAs/test.action" class="leftnavitem">

                <li>test</li>

            </a>

        </td>


what am i doing wrong here...

other links seem to be working fine.
