Unbinding a user session created using the DelegatingAuthenticator throws an LdapNoSuchObjectException

[Mike Adamson <mi...@gmail.com>]

Hi,

As the subject says, I am using the DelegatingAuthenticator to create
sessions using users on a remote Ldap server. When I unbind the session I
get an LdapNoSuchObjectException. This is because the partition nexus
attempts to lookup a partition to unbind the object.

I can't quite decide whether this is expected behaviour or a bug. I can
raise a jira issue if you think it is. My code seems to work quite happily
if I just catch the exception and ignore it.

Thanks,

Mike Adamson

This is clearly a bug. We don't handle he unbind operation in the 
authenticator classes, which is wrong, because it goes down through the 
local partition and you'll get a LdapNoSuchObjectException.

We just have to add the Unbind handling. This will be done in the next 
revision.

Thanks for the report !

Thanks Mike.

Yeah, I understand.
I think Emmanuel has found a workaround for that, in order to test the replication which also requires multiple instances of directory services, but I haven't looked at it yet.
FYI, in case you need it later, I think it's located in this class: org.apache.directory.server.replication.ClientServerReplicationIT

Ok, I've raised DIRSERVER-1662 for this.

Unfortunately a testcase or app is a little difficult because of it's
dependence on a remote Ldap instance. I couldn't see a way of using the
existing test framwork to create 2 directory services.

Thanks,

Hi Mike,

I'm not sure either, but at first sight, it looks like a bug to me.

I think it's better to open a Jira issue about it.
At least, it will help us remember the issue before cutting a next release, instead of sinking into oblivion if we only record it on the mailing list.

If possible a test case or a small class with a "main" method demonstrating the issue will help us fix the issue even quicker.

Thanks,
