>             Project: Directory ApacheDS
>          Issue Type: Bug
>          Components: core

> I have a custom Search Interceptor:
> private class SearchInterceptor extends BaseInterceptor
> When a use is said to be allowed to login, I basically inject the user into my cache:
> // We do not actually inject it, we give it to the JIT write-through
> // cache which will inject it only once, then delete after a timeout.
> //private final JitLdapWritethroughCache _jitLdapCache
> _jitLdapCache.insert(entryUser);
> Which basically does:
> // private DirectoryService service;
> service.getAdminSession().add(e);
> The line "service.getAdminSession().add(e);" basically locks up my thread (won't respond
to my search request) and won't allow any other request to go through.
> If I look at the stack, it blocks at the following line (line 390 - DefaultOperationManager)
> // Call the Add method
> Interceptor head = directoryService.getInterceptor( addContext.getNextInterceptor() );
> lockWrite();
> and 
>     public void lockWrite()
>     {
>         rwLock.writeLock().lock();
>     }
> This code all ran on the "Thread [pool-4-thread-1]" thread.
> Before running "service.getAdminSession().add(e)" I ran:
> Trace.info(service.getOperationManager().getRWLock().toString());
> Which outputted:
> 5398 [main] INFO com.rbccm.authhelper.ldap.ServerRunner  - [testinstanceid] java.util.concurrent.locks.ReentrantReadWriteLock@7177600e[Write
locks = 0, Read locks = 0]
> Thank you for your help.
