Setting up Ldap authentication

[rishikeshr]

Hi,

I am a newbie to Spring framework. As part of the project, I need to perform Ldap authentication for the user. I followed the documentation and created the following...

<bean id="contextSource" class="org.springframework.ldap.core.support.LdapContextSource">
		<property name="url" value="ldap://xxx.xxx.xxx:xxx" />
		<property name="base" value="ou=active,ou=employees,ou=people,o=xxxxxxx.com" />
		<property name="authenticationSource" ref="springSecurityAuthenticationSource" />
	</bean>
	<bean id="springSecurityAuthenticationSource"
		class="org.springframework.security.ldap.authentication.SpringSecurityAuthenticationSource" />
		
	<bean id="ldapBean" class="com.learn.authz.AuthorizeUser">
		<property name="contextSource" ref="contextSource"></property>
	</bean>

the beans using this are below:

import org.springframework.ldap.core.ContextSource;
import org.springframework.ldap.core.LdapTemplate;

public class AuthorizeUser implements UserAuthentication {
	private LdapTemplate ldapTemplate;

	public void setContextSource(ContextSource contextSource) throws Exception {
		// TODO Auto-generated method stub
		this.ldapTemplate = new LdapTemplate(contextSource);
	}

	public boolean isAuthenticated(String username, String password)
			throws Exception {
		boolean val = ldapTemplate.authenticate("", "(uid=" + username + ")",password);
		return val;
	}

}

This fails when I load the beans using ClassPathXMLApplicationContext.
I get the following error:

Caused by: org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessExceptions (1) are:
PropertyAccessException 1: org.springframework.beans.MethodInvocationException: Property 'contextSource' threw exception; nested exception is java.lang.NoClassDefFoundError: org/springframework/dao/EmptyResultDataAccessException
	at org.springframework.beans.AbstractPropertyAccessor.setPropertyValues(AbstractPropertyAccessor.java:102)
	at org.springframework.beans.AbstractPropertyAccessor.setPropertyValues(AbstractPropertyAccessor.java:58)
	at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.applyPropertyValues(AbstractAutowireCapableBeanFactory.java:1350)
	... 13 more

Am I missing any parameters in the xml configuration file?

Appreciate any pointers towards this.

Thanks,

Hi,

I managed to figure out the error. The jar file spring-tx-3.0.2.RELEASE.jar was missing from the build path. As I found out 'spring-tx.jar' supersedes the previous 'spring-dao.jar'. I was trying to include the spring-dao.jar.

Thanks,
