error while accessing through Java "javax.naming.AuthenticationNotSupportedException: simple"

Hi

I am new to openLDAP. I am configuring it (version: OpenLDAP: slapd 2.3.27) on a Linux machine to use with our Web Application (java). When I try and make a connection I am getting the following error.

===============

javax.naming.AuthenticationNotSupportedException: simple

[4/7/08 10:42:01:887 EDT] 00000026 SystemErr R at com.sun.jndi.ldap.sasl.LdapSasl.saslBind(LdapSasl.java:115)

===============

These are the code / attributes I used.

=================

Hashtable env = new Hashtable();

env.put( Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory" );

env.put( Context.PROVIDER_URL, "ldap://<machine name>:<port>" );

env.put( Context.SECURITY_PRINCIPAL, "cn=uimadmin,ou=UIM,o=nhes,dc=nh,dc=gov" );

env.put( Context.SECURITY_AUTHENTICATION, "simple" );

env.put( Context.SECURITY_CREDENTIALS, "<password in plaintext>" );

try

{

context = new InitialDirContext(env);

System.out.println("CONTEXT OPENED WITH ADMIN ACCOUNT");

}

catch (NamingException ne)

{ ne.printStackTrace();

LogManager.logMessage("LDAPManager.getAdminJndiContext()", ne);

}

return context;

=================

When I try and do an ldapsearch with a -x option (simple authentication) on the command line, it is returning results successfully. I am also able to connect using ldapbrowser v2.8.2 and see the results.

Any help regarding this is greatly appreciated.

Thanks in advance.
