Hi,
I'm giving a detailed description of my problem here

Im setting up 802.1x port based authentication using wire1x as supplicant and freeradius as the server.I have configured 
switch for 802.1x and using eap-tls as authentication protocol.freeradius is configured to authenticate the client with username and password.

My problem is i want to sent a bit(P bit) along with this username which will be taken into account for the authentication.for this i planned to send the username as P<specialcharacter>UserName.and wire1x will send the username as usual.

Now at the freeradius side i have to seperate this new user name to P and UserName.and and make the authentication as(hypothetically):

if(recieved (username,password)=(username,password)in clients.conf)&&bit P==1)
{
authenticate(return 0)
}
I found that the username,password checking is done in auth.c file.i have to add 1 more condition to that.
Hope i have explained my problem well.and hope u will give enough suggestions.
thank you

You will make the change in sites-available/default in the "authorize"
section. "man unlang" will tell you more about the language you can use in
here.

I can't give you any more detailled description of the solution, because you
haven't given a detailled description of the problem.  All you've said is
you're "sending a bit along with the username". Maybe you could give an
example of what the modified username looks like, and how you want the
username to look after restoring it?
