In my office system, Ubuntu is configured for Active Directory authentication with Windows using likewise open. I have three issues.
Each time when I switch on my system and some times when I restart, lightdm lists two users, Administrator (Ubuntu's default power user) and Guest user. So active directory accounts are not listed here. Why?
I have to login with guest and then logout to have my active directory accounts listed in the lightdm greeter. What is the reason that active directory users are loaded after a local user is logged in and then logged out?
After doing the step #2, I also get some additional users(accounts of network guys) probably those who once logged in via my machine. How to remove those undesired accounts to appear in lieghtdm user list?
