    Hi Ravi,

    i am getting below error while configure the samba client.
    Error details:
    [root@bgclient01 sbin]# mount -a
    /sbin/mount.cifs: invalid option — ‘t’

    Usage: mount.cifs -o

    Mount the remote target, specified as a UNC name, to a local directory.

    Options:
    user=
    pass=
    dom=

    Less commonly used options:
    credentials=,guest,perm,noperm,setuids,nosetuids,rw,ro,
    sep=,iocharset=,suid,nosuid,exec,noexec,serverino,
    mapchars,nomapchars,nolock,servernetbiosname=
    directio,nounix,cifsacl,sec=,sign,fsc

    Options not needed for servers supporting CIFS Unix extensions

    dev,nodev,nouser_xattr,netbiosname=,hard,soft,intr,

      Syntax what you have written in /etc/fstab file is correct but did you enabled the Firewall ports from server and SELinux context. Try to mount manually without adding an entry in /etc/fstab file use #mount //server/ShareName /mountpoint -o username=user

      while mounting you have to use share name .i.e.[mutiuser] not directory path.

    fstab entry seems incorrect. There is a comma after cifs. I reckon the two options are separate, and mount options.

    Hi Ark,

    Thanks for your tutorial. Very informative.

    Just one question: how to use the cifscreds command? I understand it is for the Samba multiuser environment, but I don’t know how to get it worked. My hypothetical environment is as follows:

    ==========
    Server Side (server.example.com)
    ==========
    1) Two Linux users: user1 user2. Both belong to group sambagroup.

    2) Added both users to Samba user database via ‘smbpasswd -a user1’ and ‘smbpasswd -a user2’

    3) mkdir /sambashare; chgrp sambagroup /sambashare; chmod 2770 /sambashare

    4) Edited /etc/samba/smb.conf accordingly. All services, firewall, and SELinux are configured properly. Shared folder can be accessed and mounted from remote clients.

    ==========
    Client Side
    ==========
    1) Add following to /etc/fstab:

    //server.example.com/sambashare /sharedfolder cifs _netdev,multiuser,credentials=/root/smbpass 0 0

    2) Added user1 login information into /root/smbpass:

    username=user1
    password=pass

    3) mount -a can mount remote folder.

    Now if I use ‘touch testfile’ in the folder, the file owner is always user1. I suppose this is where the cifscreds comes in, but don’t know how it worked. What should i do so that I can create a file under the owner user2?

    Thank you very much!
