Bug Description
My system stores uses nfs to share /home across the network. When I upgraded to 11.10, certain users could not log in via Light DM (but could log in with a simple text terminal).
When I changed the users' home directory to a file on the local machine, they were able to log in fine.
Looking at the permissions on the users home directory, all those with rwx-r-xr-x were able to log in ok, all those with rwx------ were not able to log in.
I changed the permissions on one home directory to rwxr-xr-x and that user was able to log in.
I assume that Light DM needs to be able to read something from the user's home file, and it requests data as root. Because nfs does not allow root access, it fails.
Status changed to 'Confirmed' because the bug affects multiple users.
