The error message being disaplyed is due to DirectAudit installed and the user not having a real shell defined. DirectAudit is recording user's activity on the system.
Have you tried instead of replacing the shell, adding your container logic to the logon profile instead? This should be a bit cleaner for you vs. replacing the user's shell.
