Hi
samba 4.0.5
openSUSE 12.3 cifs-utils-5.9

I have a share:
[users]
path = /home/users
read only = No

I mount it as root:

hh16:/tmp # klist

That seems fine except that the wrong uid:gid has been sent to the mount 
for steve2 so he can't write to his cifs mounted folder.

To investigate this, I made his folder 0777 and then created a file in 
the share:

hh16:/home/users # chmod 0777 steve2/
hh16:/home/users # su steve2
steve2@hh16:/home/users> cd /mnt/steve2
steve2@hh16:/mnt/steve2> touch testfile
steve2@hh16:/mnt/steve2> ls -l
total 1024
-rw-r--r-- 1 steve2 Domain Users 0 Apr 12 09:58 j
-rwxrwxr-x+ 1 3000019 users 0 Apr 12 11:14 testfile

cifs has sent 3000019:100 as the uid:gid It should send 3000034:20513

Question:
- why is user=steve specified on the mount command? (I am unix user 
steve. steve2 is a domain user, but I'm doing the mount as root)
- What am I doing wrong?

Cheers,
Steve
