a share i cant get to work right

[beef at cybertouch.org]

	Hello all,

	I have made a share that I was hopping would make it so that 
users using Microsoft word would make any new doc made by a 
user rwx for the owner of the file and for go, it would be no read, 
write, execute.

Here is the share from the smb.conf:

[mydocs]
  Comment = Microsoft Office documents directory
  path = /usr/data/mydocs
  public = no
  valid users = @user
  writeable = yes
  write list = @user
  create mask = 0700
  force create mode = 0700

Can some one tell me when i make some test files they (the 
permissions) look like this:

rwxrw-r--  1 mrsmith  user    19968 Oct  8 23:46 test2.doc*
-rwxrw-r--  1 lnb      user    19456 Oct  8 23:46 test25.doc*
-rwxrw-r--  1 lnb      user    19456 Oct  8 23:31 test3.doc*
-rwxrw-r--  1 lnb      user    19456 Oct  8 23:51 test30.doc*

Thank you,
Lanny
