I've got two near identical test scenarios - one throws exceptions the other doesn't; 1) Both access the same OpenLDAP server 2) Both running linux although slightly different kernel numbers. (one that fails is newer) 3) Both running the same release of the same version of Java 4) Both using the same compiled test class and the same jar files - not merely the same version but the same files on a single shared network drive. The only significant difference is that the one that fails has a faster network link to the LDAP server than the one that doesn't fail.

cool, let's see some ping and bing times to quantify this network congestion difference. what are the kernels and distros? s On 1 Aug 2006, at 17:16, Jon Maber wrote: > I've got two near identical test scenarios - one throws exceptions the > other doesn't; > > 1) Both access the same OpenLDAP server > 2) Both running linux although slightly different kernel numbers.

(gcc version 4.1.1 2006 0525 (Red Hat 4.1.1-1)) #1 Sat Jul 1 13:03:45 EDT 2006 I've been digging in the source code for OpenLDAP and I think it's related to poor coding in relation to handling timings. As a test of that theory I set the LDAP search timeout to infinity and the exceptions stopped. Setting the search timeout to any finite value causes exceptions on one particular client PC. Of course I also chopped out the custom Socket Factory but that made no difference at all. My sneaking suspicion is that the conversation with the LDAP server starts in one thread while another thread prepares to receive the response but the response comes back before that setup is complete. Mostly it seems to be trying to clear semaphores that don't exist and carries on executing anyway but from time to time it just locks up. |

It's not the LDAP server that's the problem - my test fails against OpenLDAP and AD directories. It's the client side that is dodgy. From home I don't have access to any AD directories so I'm testing against OpenLDAP.

I have been testing from home via BT ADSL to the Leeds AD. My ADSL is currently running at 2272 Kb/s in and 288 Kb/s out. When I try it normally, I get exceptions and timeouts. When I go in through the University of Leeds VPN, it works fine. So I don't think it is related to the speed of the connection - it works fine at 288Kb/s. Are you sure that this isn't something to do with the Leeds firewall? Aggie -----Original Message----- From: bod...@li...

Aggie, for me its the setup with the ultrafast localhost connection from the client to the server or the pretty damn fast campus connection that throw exceptions. I'm wondering whether its so fast that the Novell LDAP API timing problems are more likely to occur..

Jon, if your suspicions are correct and that the thread doesn't have time to get ready, then adding more sleeps would presumably make it worse? What happens if you remove them? Were they there to cure the original problem which went away itself? FWIW, the novell libs work fine on my laptop using openldap on localhost.

With a zero delay the exceptions come thick and fast. There's a limit to how much time I can put into studying this. In my personal opinion a good stable implementation of a network protocol should always report errors up to the application layer and not simply spew out stack traces on stderr and in the worst case silently freeze up. I have lost confidence in the Novell code. (By the way , can anyone find a bug reporting web site?) Another good reason to switch to the Sun LDAP provider is that it conforms to JNDI which is the directory equivalent of JDBC. That means if we ever experience problems with the Sun provider we can drop in another one without wasting time reprogramming to a new API - you just drop a jar file into the lib directory and edit the config file. Anyway, I realise that I'm in a minority of 1. The Leeds specific authenticator is now based on JNDI and I'm not going to switch it back to the Novell API because I need to get on with the next job. However, I'd be perfectly happy if someone else wants to rewrite it for release. Jon |
