Hello all, I have been playing with pb for a few days now and have run into a bit of a snag. I support of my pb based server I created an authorizor that did a little db based authorization. At first I had it returning the ident object, but then I realized (after a few attribute errors) that it should be returning a deffered object. Then I saw the mention of dbcred from the enterprise package. That help allot and I actually got it working by pulling some code from dbcred. At this point you could authorize yourself based on the database and make calls to the server, and all was good. At that point I was pretty happy but I noticed that within the code for dbcred it makes a call to threads.defferToTread. Me being me, I thought to myself 'I am not using threads, so why am I using this?' and I took it out. So I changed it, and am simply returning a deffered object that has a callback that returns the identity object, and it fails. In any case, I was wondering if any one had any idea of why removing the thread specific code causes it to fail. Also in a completly unrelated question, is it possible for the server to make calles on the client? I figure this is possible by passing a referencable object to the server perspective, but I thought I would get a little advice before I started playing with it.
