Comment 9 for bug 521085

OK, Samba 3.4.5, as shipped with Lucid (2:3.4.5~dfsg-2ubuntu1) solves the roaming profile problem, more or less. Windows is very picky about the precise permissions of the profile folder. The permissions on the profile folders were drwx-wx---. This worked fine for fully patched Windows XP SP3 clients and Samba 3.0.2, but no longer works with Samba 3.4.x and the same clients, giving the "windows can't load roaming profile" error messages described previously. Changing the permissions on the profile folder to drwx------ solves the problem. Note that this is NOT the same problem encountered with Samba 3.4.0. For this version, the on shipping with Karmic AMD64 Server, one can create a new profile from scratch and it will give the "window's can't load roaming profile" error message the next time the user tries to log in. I've attached the latest smb.conf file, which is not much different from the original (also attached).
