[Samba] PDC - initial profile creation

[Antony Gelberg]

I can now login to my domain from an XP Pro client, as a normal user.  Only
problem is, I get this:

Windows cannot locate the server copy of your roaming profile and is
attempting to log you on with your local profile. Changes to the profile
will not be copied to the server when you logoff. Possible causes of this
error include network problems or insufficient security rights. If this
problem persists, contact your network administrator.

DETAIL - The network path was not found.

Here are the relevant snippets:

[profiles]
path = /home/samba/profiles
read only = no
create mask = 0600
directory mask = 0700
browseable = no
profile acls = yes

[netlogon]
   comment = Network Logon Service
   path = /home/samba/netlogon
   guest ok = yes
   writable = no
   share modes = no
   browseable = no

server:~# ls -l /home/samba
total 8
drwxr-sr-x    2 root     users        4096 Jan 14 20:19 netlogon
drwxrwxrwt    3 root     users        4096 Jan 15 23:03 profiles

/home/samba/profiles is empty.  Should the user subdirectory be created when
the user first logs in?

Is there any definitive guide to the minimum required permissions /
ownership for the above two directories?  Googling gives wildly differing
answers.
