I'm running lxc on Linux Mint Debian Edition tracking Wheezy/Sid. I created a container using "lxc-create -t debian -n dev". In accordance with the Debian wiki article on LXC I have mounted the cgroups file system as /cgroup and have added "cgroup_enable=memory" to the "GRUB_CMDLINE_LINUX_DEFAULT" setting to enable cgroup memory controls (not sure if this is still required but shouldn't hurt, I'm running kernel 3.2.0-1-amd64).

After starting the container I added a user and everything seems to be fine. If I try to log into the system with the new user I get the following:

# ssh dev@dev
dev@dev's password:

Last login: Wed Feb  1 07:37:28 2012 from lxc-host
Could not chdir to home directory /home/dev: Permission denied
/bin/bash: Permission denied
Connection to dev closed.

and using su as the root user inside the system produces the following:

root@dev:~# su -c bash dev
su: User not known to the underlying authentication module

Any ideas on what I need to do to allow me to login as this user?

BTW, here's an ls of /home to show that the directory is in fact present:

root@dev:~#  ls -al /home/dev
total 12
drwxr-xr-x 1 dev  dev    54 Feb  1 07:33 .
drwxr-xr-x 1 root root    6 Feb  1 07:33 ..
-rw-r--r-- 1 dev  dev   220 Nov 30 11:01 .bash_logout
-rw-r--r-- 1 dev  dev  3085 Nov 30 11:01 .bashrc
-rw-r--r-- 1 dev  dev   675 Nov 30 11:01 .profile

Additionally here are relevant auth.log entries for the ssh attempt followed by the su attempt:

Feb  1 19:15:44 dev sshd[3599]: Accepted password for dev from 192.168.254.1 por

Necromancy comment, but what the hey. If you're still having trouble with this, run getent passwd dev and let us know the output. –  Andrew B Apr 5 '13 at 21:20
