Ubuntu : Domain user as local root

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
