Linux samba and WINDOWS File Sharing

If SAMBA is set, user a can write but cannot delete a file currently, and user B can write or delete the directory of user.

[Testdir]
Read list = puser
Writeable = yes
Write list = muping, dess120
Path =/testdir
# Force directory mode = 755
# Force group = muping
# Force create mode = 575
# Force user = muping
Create mode = 1570
# Directory mode = 1755

After setting as above, the user dess120 can write but cannot delete, but I hope that the user muping can write or delete this directory. Please kindly advise. Thank you!
