[Users] LDAP SimpleAuthentication issue.

Hi, I am new to ovirt and LDAP. Looking at adding support for Tivoli Directory Server. Here is a small java/jndi program (not using Spring LDAP) that takes IBM intranet Id and searches the directory to return IBM serial number. ********* Hashtable env = new Hashtable(); env.put("java.naming.factory.initial", "com.sun.jndi.ldap.LdapCtxFactory"); env.put("java.naming.factory.url.pkgs", "com.ibm.jndi"); env.put("java.naming.provider.url", "ldap://<ldap-server>:389"); String dn = null; try{ InitialDirContext dirContext = new InitialDirContext(env); SearchControls constraints = new SearchControls(); String[] attr = new String[] {"uid"}; constraints.setSearchScope(SearchControls.SUBTREE_SCOPE); constraints.setReturningAttributes(attr); NamingEnumeration ne = dirContext.search("ou=<ldpap-server-name>,o=ibm.com", "(mail=" + intranetID + ")", constraints); ************** But when I try to use org.ovirt.engine.core.utils.ipa.SimpleAuthenticationCheck.java, I get a "javax.naming.AuthenticationException: [LDAP: error code 49 - Invalid Credentials]" I am issuing - ldapTemplate.search("", "", contextMapper); Where contextMapper is RHDSUserContextMapper and screenshots of ldapTemplate are attached. There may be issues with the way I have setup filter and baseDN; but that should not give AuthEx. At this time I am looking for ways to get rid of authentication exception. Also, when using simple authentication, why do I need to give password? I can run "ldapsearch -LLL "(mail=<intranetID>)" -h <ldap-server>:389 -x" without password to give me expected results.
