["Stefan Seelmann (JIRA)" <ji...@apache.org>]

Stefan Seelmann created DIRAPI-342:
--------------------------------------

             Summary: Unbind breaks connection
                 Key: DIRAPI-342
                 URL: https://issues.apache.org/jira/browse/DIRAPI-342
             Project: Directory Client API
          Issue Type: Bug
    Affects Versions: 2.0.0.AM2
            Reporter: Stefan Seelmann
             Fix For: 2.0.0.AM3, 2.0.0


The DelegatedAuthIT/DelegatedAuthOverSslIT/DelegatedAuthOverTlsIT tests fail randomly (I try to stabilize tests on Windows, but also happens on Jenkins). They all do multiple bind() and unbind() on the same connection, it seems the unbind() is the reason.

A simple test to reproduce the problem (on Linux):
{code}
    @Test
    public void testSimpleBindAndUnbindLoop() throws Exception
    {
        try ( LdapConnection connection = new LdapNetworkConnection( Network.LOOPBACK_HOSTNAME,
            getLdapServer().getPort() ) )
        {
            for ( int i = 0; i < 10000; i++ )
            {
                System.out.println( i );
                connection.bind( "uid=admin,ou=system", "secret" );
                assertTrue( connection.isAuthenticated() );
                connection.unBind();
                assertFalse( connection.isAuthenticated() );
                // Thread.sleep( 10L );
            }
        }
    }
{code}

Without the unbind() or when sleeping for 10ms it works fine.

Otherwise I saw 3 different errors:

{code}
