(Linux) Configure winbind to expand nested groups

If your installation of IXIA TEXTML Server on a Linux machine uses winbind, then as the fifth task when you update a build requires you to configure winbind, allowing TEXTML Server to expand its nested groups during user authentication.

Winbind is a client-side service that resolves user and group information on a Windows server. It allows Linux to understand Windows users and groups. TEXTML Server is optimized to authenticate expanded groups. If the groups are not expanded, it may fail to authenticate users.

To configure winbind to expand nested groups:

  1. Open the /etc/samba/smb.conf file with an editor.
  2. Add the two following lines: 
    winbind expand groups = 1
winbind nested groups = yes
  3. Save and close the file.
  4. Restart the winbind service.
    Depending on your version of Linux, use one of the following commands:
    systemctl restart winbind

    -or-

    /sbin/service winbind restart
The changes are applied once the service restarts.
