[Samba] Strange behaviour with "force user" parameter

[Bruno MACADRÉ]

Hi,

I confirm that there is a bug with the force user parameter, I've tried 
with a windows 7 workstation joined to the domain.

I have this simple homes share :
[homes]
     comment = Home dir for %S
     force user = %S
     force group = %G
     create mask = 0600
     directory mask = 0700
     read only = No

The home dir of user 'foo' is /home/foo. The rights for this path are :

drwxr-xr-x 6 root root 81 août  12 17:33 /home/

drwx------ 3 foo domain users 25 août  13 09:22 /home/foo/


When I connect my user on the Win7 workstation and want to go to his 
home dir (mapped in Z:) I get a "permission denied" error message.

If I do the same with "force user" commented all work like a charm.

Am I the only one to have this bug ? Can I open a bug report about it or 
anybody knows a mysterious undocumented mechanism that lead to this 
behaviour ?

Thanks,
Regards,
Bruno
