We had the same problem as reported by mutation: a user with read-write permission not beeing able to change or delete files, another user had created.
Thinking this might be 'working as designed' we used administrator rights instead of read-write.
This however leads to other problems:
When I create a share with group A being allowed 'read' and group B as 'administrator' a user belonging to both groups cannot write in this share.
The corresponding sequenz in the smb.conf is as follows:
[share]
comment = share
path = /home/samba/shares/share
valid users = @"A", @"B"
read list = @"A"
write list =
admin users = @"B"
read only = No
browseable = Yes
force create mode = 0660
force directory mode = 0660
Right now my workaround for this is to give read-write - permission to group B as well, which results in
write list = @"B"
in the smb.conf
btw. what is the difference between 'read-write' and 'adminstrator' rights?
