I just tested on three shares
[temp]
 path= /tmp/temp
 write list = barry

[temp1]
 path= /tmp/temp1
 writeable = yes

[temp2]
 path= /tmp/temp2


If I specify the user "barry" on the mount from the client (e.g. "mount -t 
cifs //server/temp /mnt -o user=barry") then I am able to create files in 
the first two shares but not in the third.  It appears that at least on 
current 3.0.7 write list works.

Three obvious things to check - 
1) verify that you really are mounting with user id barry  (you can e.g. 
do smbstatus on the server) and that such a user exists in the server (not 
just in /etc/password but in the samba password file)
2) verify that you are not authenticating as a guest (you can do this 
various ways including using a network analyzer such as ethereal)
3) on the server itself verify that you have write permission to that 
directory as the user (on the server "cd /home/authdir" then "su barry" 
then try to create a file) since many operating systems now support more 
complex ACLs beyond the normal Unix mode bits.
