I have a problem with finding documents.
I want to configure my network like following:
1. I will use Postfix for MTA. Mail users must be login using OpenLDAP.
2. All of the usernames and passwords (mail, windows users, vpn users) must be store in Oracle DB. When a user try to login as a windows user and mail user and VPN user, he/she should use same username and password.
3. Windows machines must login using OpenLDAP via 802.1x protocol through the network active devices (switches)
4. All of connections must be in secure way.
