If one tries to connect with an illegal LDAP protocol version, no error occurs

         Key: DIRSERVER-632
         URL: http://issues.apache.org/jira/browse/DIRSERVER-632
     Project: Directory ApacheDS
        Type: Bug

    Versions: 1.0-RC3    
 Environment: Sun ONE Directory SDK for Java 4.1
ApacheDS 1.0 RC 3
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_04-b05)
Microsoft Windows XP version 5.1 Service Pack 1
    Reporter: Stefan Zoerner
    Priority: Minor


If one tries to connect to an LDAP server with a wrong version number (e.g. 4 instead of 2 or 3), it is expected that a protocol error occurs. See RFC 2251, 4.2.3, "Bind Response" for details.

This is not the case with ApacheDS, the client seems to hang instead, if you use version=4. 
Unfortunately, I was not able to create this situation with JNDI, because its LDAP Provider does not allow this operation. You can specify the version via environment (key "java.naming.ldap.version", but for an illegal value it throws an exception on the client side and does not seem to call the server at all.

Therefore I have created a JUnit test case with Sun ONE Directory SDK for Java. Netscape SDK (now Mozilla SDK, http://www.mozilla.org/directory/), will probably do as well. Please let me know, if you have any problem to reproduce  the problem.
