Cannot delete files in Samba

[Olivier Nicole]

Hi,

I recently upgraded from Samba 3.0.31 to 3.3.2 on a FreeBSD 6.4
server, and since then, the Windows machines have no right to delete
files unless the directory is "chmod o+w"

I tried to play with "map read only" and 'store dos attribues" but not
to avail.

My FreeBSD server is quite standard, the Samba cnfiguration too.

I Googled with no succees.

Any clue is much welcome.

Best regards,

Olivier
