Here is how I automatically mount CIFS share (from a remote Win2K3) without asking for a password. Architecture:

• CIFS server name : SRVDATA
• target share : Interne
• local user : damien
• mount directory: /media/srvdata/Interne

/etc/fstab

//SRVDATA/Interne /media/srvdata/Interne cifs _netdev,users,noauto,users,credentials=/home/damien/.smbcred 0 0

Note that the source is define with

//

, and that you have to be able to resolve serveur name.

• _netdev: tells fstab that this line involve a remote share.
• users: enable normal user to mount and unmount the share
• credentials : point to the file where credentials to access the share are stored.

/home/damien/.smbcred

username=login.without.domain
password=XXXXXXX
domain=DOMAIN.IN.UPPERCASE
