Title:
  Can not log in when homedir permissions are set `o-x`

Status in “lightdm” package in Ubuntu:
  New

Bug description:
  When mounting home directories over NFS with root squashing, users
  with home directories with the execute bit unset for other (i.e.
  `chmod o-x $HOME`) will not be able to log in via lightdm.  The log in
  appears to be successful, the screen blinks, and then the log in
  screen returns.  Users should be able to log in via lightdm in a root-
  squashed environment without requiring the execute bit set for
  everyone on the home directory.
