Join Ubuntu เข้ากับ Domain ด้วยการติดตั้ง โปรแกรมจาก likewise
sudo apt-get install likewise-open
หรืออยากไก้ GUI ด้วยก็ใช้คำสั่ง
sudo apt-get install likewise-open-gui
แล้วก็ Join ด้วยคำสั่ง
sudo domainjoin-cli join sci.com Administrator
จะทำให้สามารถใช้ user จาก domain ใน Ubuntu ของเราได้ แต่จะใช้คำสั่ง sudo ไม่ได้
ต้องเพิ่มรายชื่อ User เข้าไปใน sudoers file ก่อน ด้วยคำสั่ง
sudo visudo
จะได้ file /etc/sudoers.tmp เวลา save ให้ลบ .tmp ออก
ถ้าจะเพิ่ม user เดียว ก็เพิ่ม
domain\\user ALL=(ALL) ALL
หรือจะเพิ่มทั้ง User group ก็เพิ่ม
%domain\\User^Group ALL=(ALL) ALL
เช่น
%komkid\\Administrators ALL=(ALL) ALL
หรือ
%komkid\\Domain^Users ALL=(ALL) ALL

# The MySQL database server configuration file.

# You can copy this to one of:
# - "/etc/mysql/my.cnf" to set global options,
# - "~/.my.cnf" to set user-specific options.

# One can use all long options that the program supports.
# Run program with --help to get a list of available options and with
# --print-defaults to see which it would actually understand and use.
#
# For explanations see
# http://dev.mysql.com/doc/mysql/en/server-system-variables.html
# This will be passed to all mysql clients
# It has been reported that passwords should be enclosed with ticks/quotes
# escpecially if they contain "#" chars...
