How do I hide users named "Comment" from the login screen?

Banquo · 03-06-2014, 07:45 PM

After much messing about with samba, I seem to have many additional "users" added to the login list, Most are named "Comment" but one is named "Samba Guest Account"

I am using the samba gtk gui for configuring and wanted to add my linux account and my Win 7 accounts. Now I have 8 users on my linux box! How do I disable or hide them?

As you haven't mentioned your distro, i am guessing it should be ubuntu 11.10+ because it is mentioned in your profile.

Users whose userid is less than 1000 do not list in the login screen. To change the userid of the user.
# sudo usermod -u 999 user-name

If it does not work for you, follow this solution.

Open file /etc/lightdm/users.conf and add your users in the line

Code:

hidden-users=nobody nobody4 noaccess

Suppose your usernames are john david and louie, add this in the line

Code:

hidden-users=nobody nobody4 noaccess john david louie

Now restart lightdm, your users should not be disappeared on the login screen.

Slight but important note on your comment, eklavya: while you can use usermod as shown to change the numeric-userid of any user, there are two things that you must also consider:

The numeric userids should be unique. In your example, you change it to 999. You should change users according to some consistent-to-you pattern, but do not allow two users to share the same id ... and, of course, never let any of those numbers be 0.
Changing the numeric userid of a user will not affect any user sessions that are already logged on.
The home-directory of the user, and any files including hidden files in that directory and its subdirectories, must be chowned to be owned by the new numeric-id, because it is this number that actually drives the permissions system. I do not believe that usermod will change this. You can lock a user out of his own home.
