To support SSO on an instant-cloned Linux virtual machine (VM) in a VMware Horizon desktop environment, configure Samba on the golden-image Linux VM.

Use the following procedure as an example for using Samba to offline domain join an instant-cloned Linux VM to Active Directory (AD). This procedure provides the steps for an Ubuntu system.

Procedure

  1. On your golden-image Linux VM, install the winbind and samba packages. 
    sudo apt install samba krb5-config krb5-user winbind libpam-winbind libnss-winbind
    If needed, install other dependent libraries such as smbfs and smbclient.
  2. Install the Samba tdb-tools package using the following command. 
    sudo apt-get install tdb-tools
  3. Install Horizon Agent for Linux.
  4. Edit the /etc/samba/smb.conf configuration file so that it has content similar to the following example. 
    [global]
security = ads
realm = LAB.EXAMPLE.COM
workgroup = LAB
idmap uid = 10000-20000
idmap gid = 10000-20000
winbind enum users = yes
winbind enum groups = yes
template homedir = /home/%D/%U
template shell = /bin/bash
client use spnego = yes
client ntlmv2 auth = yes
encrypt passwords = yes
winbind use default domain = yes
restrict anonymous = 2
  5. Edit the /etc/krb5.conf configuration file so that it has content similar to the following example. 
    [libdefaults]
default_realm = EXAMPLE.COM

krb4_config = /etc/krb.conf
krb4_realms = /etc/krb.realms

kdc_timesync = 1
ccache_type = 4
forwardable = true
proxiable = true

[realms]
EXAMPLE.COM = {
kdc = 10.111.222.33
}

[domain_realm]
example.com = EXAMPLE.COM
.example.com = EXAMPLE.COM
  6. Edit the /etc/nsswitch.conf configuration file, as shown in the following example. 
    passwd: files winbind
group: files winbind
shadow: files winbind
gshadow: files
  7. Verify that the host name is correct and that the system date and time are synchronized with your DNS system.
  8. To inform Horizon Agent that the Linux VM is domain-joined using the Samba method, configure the following options in the /etc/vmware/viewagent-custom.conf file. Replace YOURDOMAIN with the NetBIOS name of your domain. 
    OfflineJoinDomain=samba

NetbiosDomain=YOURDOMAIN
  9. Restart the golden-image Linux VM and log back in.
