Java authentication with ldap

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://server.raleigh.basf-corp.com:389");
env.put(Context.SECURITY_PRINCIPAL, "uid=username");
env.put(Context.SECURITY_CREDENTIALS, "password");
DirContext ctx = new InitialDirContext(env);

When I try to create a new InitialDirContext, I receive the following:
[LDAP: error code 32 - No Such Object]

The error in the ldap log has the following:
BIND dn="uid=username" method=128 version=3
RESULT err=32 tag=97...
closing - B1
closed.

If I remove the uid= for the SECURITY_PRINCIPAL then I receive a error:
[LDAP: error code 34 - Invalid DN]

I have seen these errors on numerous forums, but no solution is provided. Any suggestions?

I found a solution. It happens that the ldap server that I was using had an invalid entry. I pointed to another ldap server and the problem is resolved. -ld
