4.6.1 Samba Winbind

4.6.1.1 Install or Update Required Packages

4.6.1.1.1 Samba/Winbind

The standard RHEL installation process will install the Samba/Winbind v3.x packages required for

the Linux VDA, and enable the required winbindd service. Install the required packages if not already

installed:

sudo yum -y install samba-winbind

If the packages are already installed, an update is recommended:

sudo yum -y update samba-winbind

The RHEL repositories also provide Samba v4 packages but are not installed by default. These are

not required and should not be installed.

4.6.1.1.2 Kerberos

The standard RHEL installation process will install the Kerberos v5 packages required for the Linux

VDA. Install the required packages if not already installed:

sudo yum -y install krb5-workstation

If the packages are already installed, an update is recommended:

sudo yum -y update krb5-workstation

4.6.1.2 Enable Winbind Daemon to Start on Boot

The Winbind Daemon must be configured to start on boot:

sudo chkconfig winbind on

4.6.1.3 Configure Kerberos for Winbind

By default, Winbind will not create the system keytab file /etc/krb5.keytab when joining the

domain, which implies the Kerberos tools and libraries won't be able to authenticate the machine

account.

To force Winbind to create and maintain the system keytab file and automatically renew tickets, open

/etc/samba/smb.conf and add the following entries under the [Global] section:

kerberos method = secrets and keytab

winbind refresh tickets = true

The first setting will create the system keytab when the machine is joined to the domain. If the

machine is already domain joined, you can force the creation of the keytab file by changing machine

keys:

sudo net ads changetrustpw

4.6.1.4 Join Windows Domain

This requires that your domain controller is reachable and you have a Windows account with

permissions to add machines to the domain.
