ITS#4545 bug in libldap

[hyc@symas.com]

I haven't quite figured out everything that's going on, but this patch 
definitely shows when it occurs in test036:

         if ( lr != NULL ) {
+               if ( tag == LDAP_RES_SEARCH_RESULT ) {
+                       Debug( LDAP_DEBUG_TRACE, "request done: ld %p 
msgid %ld but mis-handled!\n",
+                                       (void *)ld, (long) id, 0 );
+               }
                 ldap_return_request( ld, lr, 0 );
                 lr = NULL;
         }

The response is actually returned to the caller properly, but we never 
decide to "mark request completed." Setting a breakpoint here will let 
you poke around at it. v3ref is set to V3REF_TOAPP at this point. This 
should mean that the result included a referral and it will be returned 
to the caller, which means that we can dispose of the request, but we 
never do.
