User authentication by some couple conditions

[Tevfik Ceydeliler]

Hi,
I Use freeradius to assign IP address  by using MySQL
But due to some need I try to find some answer.

1) Is it possible one of those  two scenarios:
- Authentication by using Client AND Username+Password
- Authentication by using Usergroup AND Username+Password

2) And second question is :
Is is possible to Authentication expiration date on MySQL?

Can you give me some reference I will be really appreciated.
Regards..
