multiple MAC in calling-station-id

[Collen Blijenberg]

Just a question...

we use 'Calling-Station-Id' for authenticate agains MAC address (and 
username and passwd)

can i use multiple 'Calling-Station-Id' if some user account has, let's 
say 3 laptops.. ??

or is there an other way to link multiple mac addresses to a user account ?
------- users ------
"gebruiker"     User-Password == "12345", Calling-Station-Id == 
"00166f980e78" "00166f97d99d"
"testcase1"     User-Password == "12345", Calling-Station-Id == 
"00166f980e78 , 00166f97d99d"
"testcase2"     User-Password == "12345", Calling-Station-Id == 
"00166f980e78", Calling-Station-Id == "00166f97d99d"
-------------------
dunno somthing like this ??

Cheers

Collen...
