external script reply

[Hegedus Gabor]

Hi, I have a question,

I use external php script to get informations from the ldap.
exec getdata {
   program = .../sg.php %{User-Name}
   ..?..
}
post-auth {
   getdata
}

in the php script I do an ldap query with the argument,
and take the important data (three word) into variables.

How can I take this 3 data  back to the Tunnel-Type, Tunnel-Medium-type 
and Tunnel-Private-Group-Id items of the freeRadius.

like: $RAD_REPLY{'Reply-Message'}= 'salala'  in perl       (form wiki)

please help thanks  Gabor
