Issue with lookup resulting in a Person object

[carloscajina]

Good day,

I've been able to do what I want using dynamic filters but I'm not sure why can't make it work with the DN-based lookup (

return (Person) ldapTemplate.lookup(dn, new PersonContextMapper());

)

My beans look like this...

	<bean id="contextSource" class="org.springframework.ldap.core.support.LdapContextSource">
		<property name="url" value="ldap://ldap.some.com:389" />
	</bean>

	<bean id="ldapTemplate" class="org.springframework.ldap.core.LdapTemplate">
		<constructor-arg ref="contextSource" />
	</bean>

	<bean id="personDaoImpl" class="com.some.dao.impl.LdapPersonDaoImpl">
		<property name="ldapTemplate" ref="ldapTemplate" />
	</bean>

And the error I get is this...

I'm using anonymous access to the LDAP (just need to read data) and constructing the DN like this...

	private DistinguishedName buildDn(String uid, String ou, String o) {
		DistinguishedName dn = new DistinguishedName();	
		dn.add("uid", uid);
		dn.add("ou", ou);
		dn.add("o", o);
		
		return dn;
	}
	
	private DistinguishedName buildDn(Person person) {
		return buildDn(person.getMail(), person.getOu(), person.getO());
	}

I'm using a

ContextMapper

following the article sample in the spring-ldap distribution.

Can you spot any obvious issues?

Thanks in advance!

FIXED

it was just a matter of building the DN correctly (seems order of

dn.add(...

is key) and then

 return (Person) ldapTemplate.lookup(dn.toUrl(), getContextMapper());
