Freeradius backend for creating users

[kezern]

I have successfully installed pfsense and the captive portal using freeradius.
Now I would like a easy way for creating users. I have been searching for a time and I have found freeradius-dialupadmin and phpmyprepaid, but both of them don't seem to work on pfsense.
Is there any other way to use a backend.
I'm thinking in the possibility of creating my own backend, but first I must reconfigure freeradius to use a mysql database and I'm not user where I must change that and how to do.
