I have a somewhat odd problem. I'm using Ubuntu 10.04 and yesterday I installed and configured LDAP for centralized login. I created a new user "test" in the ldap directory. I wanted to login with that user to see if it works but I could not. There was no password prompt. What is even worse is that there is no password prompt for me as a user local to that machine (not defined in ldap). So I'm locked out of that box. What can I do to be able to log in again?
