[Samba] Problems writing to a mounted CIFS share

[Riedel, Sven]

I'm currently struggeling with a cifs mount from a windows 2003 server. The share can be mounted with mount.cifs, but despite using the rw mount option, the mountpoint can only be accessed read-only. Trying to write on the share results in a permission denied error. This happens on a 2.4.21 kernel with the shipped CIFS kernel module.

The mount command used is:
mount.cifs //<w2k3server>/<share>$ /mnt \
  -o username=<user>,workgroup=<workgroup>,password=<pwd>,file_mode=0664,dir_mode=0775,uid=<localuid>,gid=<localgid>,rw

The kernel output after enabling extended debugging:

Any help is appreciated.
