Emmanuel Lecharny resolved DIRSERVER-1814.
------------------------------------------
Resolution: Fixed
Fix Version/s: 2.0.0-RC1
Smart catch !
I have applied the patch with a slight modification (just in case the DN was
null) :
if ( !Dn.isNullOrEmpty( unbindContextDn ) )
> [patch] Using anon connection results in UnbindRequestHandler reporting
> 'LdapNoSuchObjectException: ERR_268 Cannot find a partition for '

> Debugging reveals that when using anonymous connection, DN in
> UnbindOperationContext is empty. If I connect using admin account, this
> errors stop appearing.
> This is not just a matter of printing out an exception: looking at
> UnbindRequestHandler source code, the exception is thrown from
> session.getCoreSession().unbind( unbindRequest );
> so the following lines will not be executed due to the exception:
> session.getIoSession().close( true );
> ldapServer.getLdapSessionManager().removeLdapSession(
> session.getIoSession() );
> I don't know how important are the two last ones. Please consider using Java
> 'finally' block if omitting these operations may leave server in an unstable
> state.
> To fix the bug, I suggest skipping unbind operation for an empty DN from
> UnbindOperationContext - see the attached patch. I leave UnbindRequestHandler
> changes for your own decision, as I don't know the code good enough.
