LDAP Template lookup Not Coming Back

[duffymo]

I'm trying to get the LDAP template to work for me, but without success so far.

I have an LDAP tree with the following DN:

DN: higrdn=testoe11,ou=onlineenrollment,ou=internal,dc =hig,dc=com

I get using the JXplorer LDAP browser.

I wrote a DAO to fetch this entry using the LdapTemplate lookup function. I create an LDAP DN and pass it along with an AttributesMapper. In my application context, I set the base attribute of the LdapTemplate equal to "dc=hig,dc=com".

In my first attempt at doing this lookup, I created a List of 5 RDNs and added them to my LdapName. The result was immediate:


org.springframework.ldap.EntryNotFoundException: Entry not found; nested exception is javax.naming.NameNotFoundException: [LDAP: error code 32 - No Such Object]; remaining name 'higrdn=testoe11,ou=onlineenrollment,ou=internal,d c=hig,dc=com'
Caused by: javax.naming.NameNotFoundException: [LDAP: error code 32 - No Such Object]; remaining name 'higrdn=testoe11,ou=onlineenrollment,ou=internal,d c=hig,dc=com'


The AttributesMapper is never called back. The exception is thrown by the search.

I did a search of this forum and found a thread that suggested I remove the base from the Rdn List. When I did that, the application ran for five minutes without bringing anything back.

What am I missing? Here's the finder method I've implemented:


public User findByUserHigRdn(String userHigRdn)
{
User user = null;
LdapName dn = null;

try
{
List<Rdn> rdns = new ArrayList<Rdn>();

// Per http://forum.springframework.org/showthread.php?t=28467&highlight=lookup - remove base from RDN
/*
rdns.add(new Rdn("dc", "com"));
rdns.add(new Rdn("dc", "hig"));
*/
rdns.add(new Rdn("ou", "internal"));
rdns.add(new Rdn("ou", "onlineenrollment"));
rdns.add(new Rdn("higrdn", userHigRdn));

dn = new LdapName(rdns);

logger.debug("dn: " + dn);

AttributesMapper userMapper = new UserAttributesMapper();

user = (User)ldapTemplate.lookup(dn, userMapper);
}
catch (InvalidNameException e)
{
logger.error("dn: " + dn, e);

throw namingExceptionTranslator.translate(e);
}

return user;
}
}


Thanks for your help. - %

Found my problem: I had a very bad AttributeMapper implementation. I was iterating over the NamingEnumeration when I should have just been getting the values out of the Attributes. Mea culpa.
