How do I enable the “Other” user for login with Active Directory?

Question

So I work at a university using active directory, and in my office there are a few computers that I've set up, in Ubuntu 11.10, to log as an AD user.

In order to log in a person just needs to use the "other" user at login and use their university ID and Password. I've installed 12.04LTS on my personal computer, and I see that the "other" option no longer exists.

If I upgrade those computers who need AD login capabilities, will they have them?

Answer 1

Edit /etc/lightdm/lightdm.conf and add the following line :

greeter-show-manual-login=true

Then restart lightdm :

sudo service lightdm restart

Answer 2

You can also hide all users so that you enter whatever name you want by editing /etc/lightdm/lightdm.conf adding :

greeter-hide-users=true

This is particularly useful if you use NIS or LDAP services.
