[CentOS] Prompt for chrooted users

We have a requirement to allow ssh access to a server in order to provide a secure link to one of our legacy systems. I would like to chroot these accounts.

I have this working except for one small detail, the user's prompt in the ssh session. Each user has their shell set to /bin/bash in /etc/passwd. However, instead of getting the prompt defined in their .bash_profiles we see this:

-bash-4.1$

when we are expecting this:

[username@hostname dir]$

So, before I go messing around moving files I would some information from you as tio what I have overlooked. Do I need to move something like etc/passwd and /etc/group into the chroot/etc?

TIA
