How Can I use local /etc/passwd users for 802.1x authentication

[Aydın KOÇAK]

Hello ;
I need authenticate local /etc/passwd users with FreeRadius for wired and wireless network 802.1x authentication ?
Is it posible ?

Or i can migrate all local users to ldap server in this case is it posible ? Because i dare say 802.1x authentication not correctly work with encrypted password on ldap ?

Could You please give information about this issue ?
