Hi,

Thanks to http://wiki.freeradius.org/PopTop i can authenticate my vpn users
using an remote radius server using MS-CHAPv2
Passwords are stored in clear in the mysql database.
PopTop is responsible for the remoteip.
Everything works.
Now, is it possible?
* to use md5 passwords in db; i had this in the first place but
authentication failed

CHAP requires passwords to be stored in plaintext on the backend.

* achieve the following: user A is logged in from workstation X; dont let
him log in from workstation Y as long he is logged in from X
