[Samba] How to stop creation of read-only files?

Hi everyone,

I've discovered an odd problem in Samba where I can apparently create a
read-only file even though I thought I'd disabled this (primarily
because once you make the file read only, you then can't delete it

The relevant section of smb.conf:

    create mask = 664
    directory mask = 775
    force security mode = 660
    nt acl support = yes
    inherit acls = yes
    inherit owner = yes

If I create a file normally and try to mark it read-only it correctly
tells me 'access denied', however if I create a file elsewhere, mark it
read-only there and then copy it across to the Samba share, the file is
created in read-only mode which means I then can't delete it again.

Is this a bug in Samba or am I missing an option in my share config?
This is with Samba 3.0.21rc2.
