Title:
  Cannot log in with more passwd entries with the same UID

Status in Light Display Manager:
  New
Status in “lightdm” package in Ubuntu:
  New

Bug description:
  I am not sure if it's a bug, however this works on the text console
  without problem since years.

  Yes, that is ugly, I know: sometimes I need to test (while developing)
  softwares run as a specific unix user. To make this simple I often
  used the trick to add a line to /etc/passwd with different user name
  but the same numeric uid/gid as my account used to log in at lightdm's
  prompt. Usually I remove that line then, but I forgot it, and after
  reboot I couldn't log in.

  According to /var/log/lightdm/lightdm.log lightdm treated as I want to
  use as this "phantom" user, which is not true. Using simple console
  login there is no such a problem.

  AFAIK it's not so nice/legal to use /etc/passed entries refeering for
  the same unix numerical uid, so I am not sure if it's a bug which
  should be fixed, or it's something I shouldn't do, but as I've written
  above, it works (and always worked since 1995 on
  Debian/Ubuntu/Slackware/RedHat systems - as far as I can recall) on
  console logins at least.

  By the way, I haven't added /etc/shadow entry for the user, only
  /etc/passwd. And of course I tried to log in with my "normal" user,
  not the "phantom".

  thanks!
