NameNotFoundException when I switch from LdapContextSource to PoolingContextSource

My searches start throwing NameNotFoundException when I switch from LdapContextSource to PoolingContextSource, can someone help?

Exception:
ServiceInvocationError:org.springframework.ldap.Na meNotFoundException: [LDAP: error code 32 - No Such Object]; nested exception is javax.naming.NameNotFoundException: [LDAP: error code 32 - No Such Object];


Code:
result = ldapTemplate.search(base.toString(), andFilter.encode(), SearchControls.OBJECT_SCOPE, new String[] { "cn", "imCountry", "preferredLanguage", "preferredDeliveryMethod", "telephonenumber", "mail","imCompanyID" }, new AttributesMapper()

Configuration that works:

<beans:bean id="contextSourceTarget"
class="org.springframework.ldap.core.support.LdapC ontextSource">
<beans:property name="url" value="ldap://spogtamldap-ro:389" />
<beans:property name="userDn"
value="uid=tcserver-ro,ou=applications,dc=ironmountain,dc=com" />
<beans:property name="password" value="${TAM.LDAP.password}" />
<property name="dirObjectFactory" value="org.springframework.ldap.core.support.Defau ltDirObjectFactory" />
<property name="pooled" value="false" />
</beans:bean>
