The TACACS virtual server's function

[黄立成]

Hi guys, I am writing to ask some questions about the TACACS SERVER in version 4.x.x.  I would like to know how can I do things I did in radius server.Things looks different in tacacs.
1)enable authentication
2) authorization privilege level for each user.
3) authorization network attributes.
4) authorzation specific commands.
The common things  in 1) 2) 3) I want to do is making different rules for different users.In radius,AUTHOR COMES AFTER AUTHEN,so I just need to set these attributes in USERS file.
I am wondering if there is simple configuration I can do or interfaces I can use just like what I did in radius.
I am confused because I cannot find an example to follow.I WISH YOU COULD PROVIDE ME A SAMPLE CONFIGURATION FOR TACACS,that will be the best!!

THANKS FOR YOUR HELP！
