How do you add LDAP users to greeter

Question

I have LDAP running successfully and can log in successfully as an LDAP user either from tty or Terminal after logging in as another user. How can I log into the graphical environment as an LDAP user?

My default admin account and a local, standard account for testing both appear on the Greeter screen after boot but LDAP users don't.

My preference is to display only LDAP users who have already logged in on the machine and have a home directory rather than every user in LDAP.

You will need to create a custom configuration file to accomplish this goal.

Here's how you do it:

0. Open Terminal (if it's not already open)
1. Create a new directory for some LightDM configurations (if it doesn't already exist):

   sudo mkdir /etc/lightdm/lightdm.conf.d
   

2. Create a custom configuration file:

   sudo vi /etc/lightdm/lightdm.conf.d/50-custom.conf
   

3. Paste the following into the new file:

   [SeatDefaults]
   greeter-show-manual-login=true
   allow-guest=false
   

4. Restart LightDM:

   sudo service lightdm restart
   

You will now see a "Manual Login" option at the bottom of the screen:

Click on that and ...

There you go 👍🏻
