[cas-user] Limiting mapped Response results

[Dale]

Hello,

Is it possible to limit the responses a mapped result returns?

To clarify my intention....

I have setup deployerConfigContext.xml with the following mappings..

<bean id="attributeRepository" 
class="org.jasig.services.persondir.support.ldap.LdapPersonAttributeDao"> 
==Truncated==
<property name="resultAttributeMapping">
      <map>
        <!-- Mapping between LDAP entry attributes (key) and Principal's 
(value) -->
        <entry key="uid" value="netid"/>
        <entry key="userPIDM" value="UDC_IDENTIFIER"/>
        <entry key="cn" value="commonName"/>
        <entry key="mail" value="mail"/>
        <entry key="mailHost" value="mailHost"/>
        <entry key="uid" value="nameidentifier"/>
        <entry key="givenName" value="givenname"/>
        <entry key="sn" value="surname"/>
        <entry key="userPIDM" value="studentid"/>
      </map>
    </property>

I have also 
setup "WEB-INF/view/jsp/protocol/2.0/casServiceValidationSuccess.jsp" with 
the following

<cas:serviceResponse xmlns:cas='http://www.yale.edu/tp/cas'>
 <cas:authenticationSuccess>
  
<cas:user>${fn:escapeXml(assertion.chainedAuthentications[fn:length(assertion.chainedAuthentications)-1].principal.id)}</cas:user>
  <cas:attributes>
    <c:forEach var="auth" items="${assertion.chainedAuthentications}">
     <c:forEach var="attr" items="${auth.principal.attributes}" >
      
 
<cas:${fn:escapeXml(attr.key)}>${fn:escapeXml(attr.value)}</cas:${fn:escapeXml(attr.key)}>
   </c:forEach>
</c:forEach>

   </cas:attributes>

This returns as expected for all mappings except for <entry key="uid" 
value="nameidentifier"/>
which returns an array of values <cas:nameidentifier>[dsallis, 
dsallis_student, dsallis_admin]</cas:nameidentifier>

Returning to my question, Can this return be limited to just the first 
result "dsallis"?

Thank you,
D.Sallis
