[cas-dev] Custom Attribute Resolver.. help needed.

[Sean R. McNamara]

Hi all,

I'm working to develop a custom attribute resolver, and am more or less 
following the model given by 
CredentialsToLDAPAttributePrincipalResolver.java.


I've built a custom Credentials -> Principal resolver, 
CredentialsToDNDFieldPrincipalResolver
a custom PersonAttributeDao, DNDPersonAttributeDao,

and have configured the deployerConfigContext.xml as follows:

                [.....]
                <property name="credentialsToPrincipalResolvers">
                        <list>
                                <bean
                                        
class="org.jasig.cas.authentication.principal.CredentialsToDNDFieldPrincipalResolver">
                                        <!-- The Principal resolver form 
the credentials -->
                                        <property 
name="credentialsToPrincipalResolver">
                                                <bean 
class="edu.dartmouth.cas.authentication.principal.DartmouthUsernamePasswordCredentialsToPrincipalResolver" 
/>

                                        </property>
                                        <!-- The query made to find the 
Principal ID. "%u" will be replaced by the resolved Principal -->
                                        <property name="filter" 
value="%u" />

                                        <!-- The attribute used to 
define the new Principal ID -->

                                        <property 
name="principalAttributeName" value="name" />

                                        <property 
name="attributeRepository">
                                                <ref 
bean="attributeRepository" />
                                        </property>

                                </bean>
                [.....]

        <bean id="attributeRepository"
                
class="org.jasig.services.persondir.support.dnd.DNDPersonAttributeDao">
                <property name="fieldsToAttributes">
                        <map>
                                <entry key="lastname" value="lastname" />
                                <entry key="firstname" value="firstname" />
                                <entry key="name" value="name" />
                        </map>
                </property>
        </bean>



The code compiles, and according to some debug I've inserted into the 
code, successfully builds the Principal and populates the attributes, 
however, in casServiceValidationSuccess.jsp, when I attempt to access 
the attributeMap as follows:

/<cas:user>${fn:escapeXml(assertion.chainedAuthentications[fn:length(assertion.chainedAuthentications)-1].principal.id)}</cas:user>/
<c:forEach var="auth" items="${assertion.chainedAuthentications}">
<c:forEach var="attr" items="${auth.principal.attributes}" >
<cas:attribute name="${fn:escapeXml(attr.key)}" 
value="${fn:escapeXml(attr.value)}"/>
</c:forEach>
</c:forEach>

I only see the <cas:user>...</cas:user> data in my response.    I 
verified I'm modifying the correct .jsp, so, I know that's not an issue.


I'd appreciate any assistance anyone could offer.  I'm a little stumped 
at this point.     One thing I haven't done and I'm not clear whether or 
not is a necessary step to get this to work, is to enable the Services 
support (http://www.ja-sig.org/wiki/display/CASUM/Configuring) or 
whether that's irrelevant unless I'm looking to use the whitelisting 
features..

Thanks for  your help..

..Sean.
