What's wrong with my login process?

  • 772
  • I installed and configured a test server with OpenLDAP and created a user with username (uid) "jdoe", following some of the guide at: https://help.ubuntu.com/lts/serverguide/openldap-server.html.
  • I used phpLDAPadmin to create my OUs and users.
  • I installed and configured libnss-ldap per the guide.
  • I can su - jdoe and it works okay.
  • I configured /etc/lightdm/lightdm.conf to show a manual login.
  • I could log in to Ubuntu graphically (with the LightDM greeter) as "jdoe", until changing jdoe's uid to 5000. I changed this because I noticed his and my uids were both set to 1000, which I think caused some weird issues. Now, when I try logging in graphically as jdoe, I get a sound and the screen flashes, but it does not log jdoe in to his Ubuntu desktop. I noticed when I create a new user in phpLDAPadmin, their uid defaults to 1000 - the same as my uid... Is this how it's supposed to work?

    I figured out that there is a setting in /etc/phpldapadmin/config.php of auto_number...

    I set:
    $servers->setValue('auto_number','enable',true);
    $servers->setValue('auto_number','mechanism','search');
    $servers->setValue('auto_number','min',array('uidNumber'=>5000,'gidNumber'=>5000));

    I could then log in with both su - and via the graphical shell.
