I have CAS 4.0.7 running and I'm testing using a different value from LDAP to
authenticate with a service that uses the SAML 2.0 (Google Apps) support
provided by CAS. I would like to use the employeeID attribute from Active
Directory as the principal Id for this service only. I have tried this setup:
Setup in deployerConifgContext.xml file:
<bean id="attributeRepository"
class="org.jasig.services.persondir.support.StubPersonAttributeDao"
p:backingMap-ref="attrRepoBackingMap" />
<util:map id="attrRepoBackingMap">
<entry key="uid" value="uid" />
<entry key="mail" value="mail" />
<entry key="employeeID" value="employeeID" />
</util:map>
<bean class="org.jasig.cas.services.RegexRegisteredService">
<property name="id" value="5" />
<property name="name" value="---service name---" />
<property name="description" value="---service description---" />
<property name="serviceId" value="---server url---" />
<property name="evaluationOrder" value="5" />
<property name="usernameAttribute" value="employeeID" />
<property name="allowedAttributes">
<list>
<value>employeeID</value>
</list>
</property>
</bean>
<bean id="ldapAuthenticationHandler"
class="org.jasig.cas.authentication.LdapAuthenticationHandler"
p:principalIdAttribute="sAMAccountName"
c:authenticator-ref="authenticator">
<property name="principalAttributeMap">
<map>
<!--
| This map provides a simple attribute resolution mechanism.
| Keys are LDAP attribute names, values are CAS attribute names.
| Use this facility instead of a PrincipalResolver if LDAP is
| the only attribute source.
-->
<entry key="displayName" value="displayName" />
<entry key="mail" value="mail" />
<entry key="employeeID" value="employeeID" />
</map>
</property>
</bean>
Setup in the argumentExtractorsConfiguration.xml file:
<bean id="googleAccountsArgumentExtractor"
class="org.jasig.cas.support.saml.web.support.GoogleAccountsArgumentExtractor"
p:privateKey-ref="privateKeyFactoryBean"
p:publicKey-ref="publicKeyFactoryBean"
p:alternateUsername="employeeID" />
However, in the SAML assertion that comes from CAS, the name id that is sent
over is just the text "employeeID" instead of the actual employee ID attribute
in Active Directory. Any thoughts on why it isn't sending the employee ID
value? If I remove the alternateUsername field from the
googleAccountsArgumentExtractor, then CAS does send over the sAMAccountName
like it normally should.
Thanks,
David Abney
