I am trying to mount the lenovo nas device on my server (sles 11 sp3). with below command

#mount -t cifs //10.0.223.25/public /mnt/storage -o username=admin,password=password,file_mode=0777,di r_mode=0777

It gives the error

mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

same command has been working fine other sles servers.

Kindly help
