*I want to run CAS with JDBC backend. I've succeeded to use simple
authentication (login and password). The problem is that I need to add
another attribute (such as group), so that it will be returned in the
XML success response.*
*Here is the *deployerConfigContext.xml* (only important parts):*
...
...
<bean
class="org.jasig.cas.authentication.principal.UsernamePasswordCredentialsToPrincipalResolver"
>
<property name="attributeRepository">
<ref bean="attributeRepository"/>
</property>
</bean>
<bean
class="org.jasig.cas.adaptors.jdbc.SearchModeSearchDatabaseAuthenticationHandler"
>
<property name="dataSource" ref="dataSource"/>
<property name="passwordEncoder" ref="passwordEncoder"/>
<property name="fieldUser" value="login"/>
<property name="fieldPassword" value="password"/>
<property name="tableUsers" value="user"/>
</bean>
</list>
</bean>
...
...
<bean id="attributeRepository"
class="org.jasig.services.persondir.support.jdbc.SingleRowJdbcPersonAttributeDao">
<constructor-arg index="0" ref="dataSource"/>
<constructor-arg index="1">
<list>
<value>login</value>
</list>
</constructor-arg>
<constructor-arg index="2" value="SELECT group FROM user WHERE
login='?'"/>
<property name="columnsToAttributes">
<map>
<entry key="group" value="group" />
</map>
</property>
</bean>
...
...
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource"
p:driverClassName="com.mysql.jdbc.Driver"
p:url="jdbc:mysql://localhost:3306/CAS"
p:username="cas"
p:password="password" />
*I've also modified the *casServiceValidationSuccess.jsp* to handle
the new attribute:*
<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>
*The problem is that when I enter a valid user credentials, I get this
exception:*
action execution attributes were 'map['method' -> 'submit']'; nested
exception is java.lang.NullPointerException
