I'm using openladap version 2.2.17 under SUSE-Linux. The Java-application runs
with jdk 1.4.2_6 on WinXP SP2.
I'm using the LDAP Booster Pack 1.0.
Here is a short sequence of my programm...

Hashtable env = new Hashtable();
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, "cn=manager, dc=thyssenkrupp, dc=com");
env.put(Context.SECURITY_CREDENTIALS, "anfang");
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://servername:389";);
env.put("java.naming.ldap.version", "3");
env.put("com.sun.jndi.ldap.connect.pool", "true");

try
{
       	// create context
       	LdapContext ctx = new InitialLdapContext(env, null);
	
	// looking what is all supported
       	Attributes attrs = ctx.getAttributes( URL, 
                              new String[]{"supportedcontrol"}); 
       	System.out.println(attrs); // Close the context when we're done 

        Control[] ctxCtls = new Control[]{ new PagedResultsControl( 5 ) };
        ctx.setRequestControls( ctxCtls);

        //Perform the search by using the original context
	NamingEnumeration answer = ctx.search("ou=user,dc=mydomain,dc=com", 
                "(sn=*)", null);

	//Enumerate the answer
        while (answer.hasMore()) 
	{
	            SearchResult sr = (SearchResult)answer.next();
		...
        }

}
catch(Exception exc)
{
       	exc.printStackTrace();
}

If I run this code I get following output:

{supportedcontrol=supportedControl: 
	2.16.840.1.113730.3.4.18, 
	2.16.840.1.113730.3.4.2, 
	1.3.6.1.4.1.4203.1.10.1, 
	1.2.840.113556.1.4.1413, 
	1.2.840.113556.1.4.1339, 
	1.2.840.113556.1.4.319, 	the server does support pagedResultsControl
	1.2.826.0.1.334810.2.3}
javax.naming.OperationNotSupportedException: [LDAP: error code 12 - control
unavailable in context]; remaining name 'ou=groups,dc=mydomain,dc=com'

	at javax.naming.directory.InitialDirContext.search(Unknown Source)
	at com.gft.tk.model.database.ldap.TestLdap.testFetching(TestLdap.java:240)

The exception I get in the call of ctx.search(...).
The message I think means that the server doesn't support pagedResultsControl.

This is a contradiction to the received list of supported controls.
What's the matter?
