Description

Installs and configures Samba version 3 to work with kerberos and Windows active Directory

Requirements

Assumes Samba version 3.

Should work on Debian-family, Red Hat-family and ArchLinux systems.

Uses Chef Server for data bag to build configuration file shares.

This cookbook connect to Windows Active Directory via Kerberos

The "/etc/samba/smbusers" file maps unix user names to Active Directory logons

The actual authentication is done by Kerberos

Limitations

Does not (yet) integrate with LDAP/AD.

Uses plaintext passwords for the user data bag entry to create the SMB users if the password backend is tdbsam or smbpasswd. See below under usage.

Does not modify the Samba daemons to launch (i.e., ArchLinux's /etc/conf.d/samba SAMBA_DAMONS).

Attributes

The attributes are used to set up the default values in the smb.conf, and set default locations used in the recipe. Where appropriate, the attributes use the default values in Samba.

• node["samba"]["workgroup"] - The SMB workgroup to use, default "SAMBA".
• node["samba"]["interfaces"] - Interfaces to listen on, default "lo 127.0.0.1".
• node["samba"]["hosts_allow"] - Allowed hosts/networks, default "127.0.0.0/8".
• node["samba"]["bind_interfaces_only"] - Limit interfaces to serve SMB, default "no"
• node["samba"]["server_string"] - Server string value, default "Samba Server".
• node["samba"]["load_printers"] - Whether to load printers, default "no".
• node["samba"]["passdb_backend"] - Which password backend to use, default "tdbsam".
• node["samba"]["dns_proxy"] - Whether to search NetBIOS names through DNS, default "no".
• node["samba"]["security"] - Samba security mode, default "user".
• node["samba"]["map_to_guest"] - What Samba should do with logins that don't match Unix users, default "Bad User".
• node["samba"]["socket_options"] - Socket options, default "TCP_NODELAY"
• node["samba"]["config"] - Location of Samba configuration, default "/etc/samba/smb.conf".
• node["samba"]["log_dir"] - Location of Samba logs, default "/var/log/samba/%m.log".

Recipes

client

Installs smbclient to provide access to SMB shares.

default

Includes the client recipe by default.

server

Sets up a Samba server. See "Usage" below for more information.

Usage

The samba::default recipe includes samba::client, which simply installs smbclient package. Remaining information in this section pertains to samba::server recipe.

Set attributes as desired in a role, and create a data bag named samba with an item called shares. Also create a users data bag with an item for each user that should have access to samba.

Example data bag item for a single share named export in the shares item.

% cat data_bags/samba_shares/logs.json
{
  "id": "logs",
  "comment": "Everybody loves logs",
        "path": "/logs",
        "guest ok": "no",
        "printable": "no",
        "read list": [ "infosec" ],
        "write list": ["jtimberman"],
        "create mask": "0664",
        "directory mask": "0775"
}

Example data bag item for a user. Note that the user must exist on the system already. This is the minimal users data bag to set up the smbpasswd entry. More options are available for those using the users cookbook, see the readme for that cookbook for more information.

% cat data_bags/users/jtimberman.json
{
  "id": "jtimberman",
        "groups": [ "developers", "infosec" ],
        "ad_domain": "BIG_CORP_HQ"
}
