javax.naming.AuthenticationException: [LDAP: error code 49 - Invalid Credentials]

I'm new to ldap and I was trying what I thought was a trivial example to test the spring ldap module with an ldap instance that someone had already setup for testing. Details about the ldap instance that I am using can be found here: http://blog.stuartlewis.com/2008/07/07/test-ldap-service/comment-page-3/ I've used an ldap browser/admin tool (Softerra LDAP Admin) and I can access the directory without any issues. When I try it using java and spring-ldap (2.0.1) I get the Authentication Exception mentioned above. Before setting up my own ldap instance to try and troubleshoot this further I wanted to check here in case someone with more experience could point out something obvious that I missed. Below is the code I am using: ``` import org.springframework.ldap.core.LdapTemplate; import org.springframework.ldap.core.support.LdapContextSource; import java.util.List; public class LdapTest { public List<String> getListing() { LdapTemplate template = getTemplate(); List<String> children = template.list("dc=testathon,dc=net"); return children; } private LdapTemplate getTemplate(){ LdapContextSource contextSource = new LdapContextSource(); contextSource.setUrl("ldap://ldap.testathon.net:389"); contextSource.setUserDn("cn=john"); contextSource.setPassword("john"); try { contextSource.afterPropertiesSet(); } catch (Exception ex) { ex.printStackTrace(); } LdapTemplate template = new LdapTemplate(); template.setContextSource(contextSource); return template; } public static void main(String[] args){ LdapTest sClient = new LdapTest(); List<String> children = sClient.getListing(); for (String child :children) { System.out.println(child); } } } ``` Stack trace: ``` Exception in thread "main" org.springframework.ldap.AuthenticationException: [LDAP: error code 49 - Invalid Credentials]; nested exception is javax.naming.AuthenticationException: [LDAP: error code 49 - Invalid Credentials] at org.springframework.ldap.support.LdapUtils.convertLdapException(LdapUtils.java:191) at org.springframework.ldap.core.support.AbstractContextSource.createContext(AbstractContextSource.java:356) at org.springframework.ldap.core.support.AbstractContextSource.doGetContext(AbstractContextSource.java:140) ```
