If i edit /etc/ppp/chap-secrets and give it a username passwd etc it will work fine and the user will authenticate with no problem.
But i want to use tacacs+ for authorization so it can authorize users that are in the /etc/shadow file.
the log file is this :

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
i've installed poptop and it works great.
If i edit /etc/ppp/chap-secrets and give it a username passwd etc it will work fine and the user will authenticate with no problem.
But i want to use tacacs+ for authorization so it can authorize users that are in the /etc/shadow file.
