I mounted a windows share as root using the command

mount -t cifs //windows_server/file_path -o noperm,rw,username=svc-live-oo,credentials=/etc/cifspw /mnt/windows_data/migration

I ensured from the windows security that "Everyone" has write access to this directory.

When I try to run touch a as root at /mnt/windows_data/migration, I get an error - touch: cannot touch `a': Permission denied
I confirmed that the migration folder has 777 permissions on it.

Based on some google serach, I tried umount and mount with following combinations of noperm and rw, but none helped. I continue to get the same error. What am I missing?

mount -t cifs //windows_server/file_path -o rw,username=svc-live-oo,credentials=/etc/cifspw /mnt/windows_data/migration

mount -t cifs //windows_server/file_path -o noperm,username=svc-live-oo,credentials=/etc/cifspw /mnt/windows_data/migration

mount -t cifs //windows_server/file_path -o noperm,rw,username=svc-live-oo,credentials=/etc/cifspw /mnt/windows_data/migration

Thanks for all the help and suggestions.

Never mind, I figured it out

On the windows box, click on the properties and navigate to sharing tab. Click on the Permissions button "To set permissions for users who access this folder over the network". Enable the appropriate permissions for the users/groups in this dialog. In my case, I gave Everyone Full Control, though that is not recommended.

Hope this helps.
