Title:
  lightdm login fails with NFS home and strict (mode 0700) permissions

Status in Light Display Manager:
  Confirmed
Status in “lightdm” package in Ubuntu:
  Triaged
Status in “lightdm” source package in Oneiric:
  Triaged

Bug description:
  Lightdm appears not to be able to log in a user if all of the
  following are true:

  1.  They've got an NFS-mounted home directory
  2.  NFS is configured in the usual manner; ie, root privileges do not allow access to arbitrary remote files
  3.  The user's home directory permissions are such that "other" cannot access the directory (ie, mode 0700)

  In this situation, the password is accepted and the screen clears.
  Rather than bringing up the desktop as expected, a couple of seconds
  pass and we're returned to the lightdm screen.  This yielded a message
  in one of the /var/log/lightdm logs which I've just discovered was
  overwritten by subsequent successful logins.  I'll recreate this and
  update the bug tonight.

  Workaround was to chmod the user's homedir to 0711 which allowed
  lightdm to work properly.

  Release is Ubuntu 11.10 with all updates as of 17 Oct 2011 at roughly
  10pm EDT.  Lightdm package is 1.0.1-0ubuntu6.
