I am setting up a domain controller using Fedora core 6 and Samba 3.0.24-7. Windows XP Pro SP2 machines are able to join the domain, and users can login to the domain from Windows. I am having difficulty getting roaming profiles to work, however.
Here is the procedure I have tried to setup a roaming profile:
1. mkdir /export/samba/profile/jjacko
2. chown jjacko /export/samba/profile
3. login from windows machine. Everything seems to work beautifully.
4. logoff from windows machine. Receive error message that "Windows cannot update your roaming profile..."
5. an empty file, prf217.tmp, now exists in my profile directory on the samba server, owned by jjacko.staff, permissions 640
6. Subsequent login attempts display the error message: "Windows cannot copy file \\Samba server\profile\jjacko\prf217.tmp to location C:\Documents and Settings\jjacko\prf217.tmp. ... DETAIL - Access is denied." I am then logged onto windows with a temporary profile.

Obviously I have some problem with permissions/ownership, but I can't figure it out. Any suggestions? I am also including smb.conf below. Thank you for your help.
