Configure winbind to expand groups (Linux)

If your installation of IXIA TEXTML Server on a Linux machine uses winbind, then you must configure winbind to allow TEXTML Server to expand its nested groups when authenticating users.

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 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.
