[Samba] Problem with folder redirection and "guest user"

Hi all,

I am setting up my second server with Samba 3.0.21c with LDAP as described in
Samba3-ByExample. The server OS is Slackware Linux 10.2, without PAM.

All seemed to work perfect until I decided to try folder redirection.
I followed the instructions given in the "happy users" chapter, but now new
users cant log in. When trying to log in with a new user (umgrtest16) from a
WinXP SP2 client, I get a error message about "Windows cannot log you on
because your profile cannot be loaded".
When I look in the Samba log for the computer I tried to log in from (s100$),
I find that Samba is trying to do something as the "guest" user.
" guest user (from session setup) not permitted to access this share (profdata)"
See more of the log below.

To further test this, I set "guest ok = yes" on the profdata share, and try to
log in as the new user again. Now the new user can log in!

The problem is that the folder containig the redirected folders
(\\SOT01\profdata\umgrtest16) and all its content are owned by the user
"nobody", and the group "Domain Guests".

The home and profile folders and all their content are owned by
umgrtest16.Domain Users.

I am struggling with figuring out why I must set "guest ok = yes".
Is there anybody out there that can give me any kind of help with this?


Please excuse my English, it is  not my native tongue.

Regards
Joran Kvalvaag
