Seems to me like you can solve this by opening the right ports on your firewall(s) and configuring a route (on your network) from your DMZ to your Domain Controller(s) for traffic on those ports.

Here's the list of ports used to communicate with Domain Controllers:

Unfortunately I'm not a Linux guru, nor do I know which type and version of distro you use so I can't give you any instructions how to specifically add those to your domain.

Can you clarify exactly what you need help with and what distro are you using? Take a look of this reference and it get you started.

You can leave the Linux server in the DMZ.  You need to configure windbind and pam.  This document may help you:

You may also need to configure nss, kinit, and kerberos.  If you leave it in the DMZ and it is supporting a website, you should have an IDS installed.  You may want to harden the Linux server too (implement IP tables, disable services you don't need, have strict password policies, review logs in /var/log/, turn on SELinux ideally disable any GUI desktop etc.).
