Leopard Authenticating to Tiger Server

Hi Guys, Hopefully there are a few people who have already had some experience with this since Leopard's been in the wild. I am loving leopard on my iMac, and I have begun preparing to deploy to one of my labs. I set up Directory Utilities to access my 10.4.10 Tiger server. When I attempt to log in it takes a very long time (about 2 minutes). I did have a problem with Tiger clients not logging in properly, and was helped out by this - [url]https://www.afp548.com/forum/viewtopic.php?forum=18&showtopic=16657[/url] Could it be something similar to do with automounting? I had a poke around for similar files but couldn't find them. Once logged in, I am able to access the users home directory, but I do not receive the preferences I set up in WGM. Users are able to open up applications that they shouldn't, and don't receive the custom dock I specified. However, when logged in as a local user such as the administrator they receive appropriate WGM settings. I tried zapping the pram and reissuing the settings, but to no avail. Surely I couldn't be the only person experiencing this? Anyone who has been playing... please help!!
