VSA and other attributes in Access-Accept

[Mohammed Petiwala <mhpetiwala@yahoo.com>]

Hi:
  Could anyone please provide me some advice on my question below.
  Currently I am seeing VSAs in my reply messages from freeRADIUS being  passed in Access-Accept, Access-Challenge. I would like to limit  certain VSAs to only Accepts, or Challenge. 
  Is this possible - because according to the RFCs for 3GPP/3GPP2 only some of them are possible in certain type of responses.
  Thx.
  
  Regards,
  Mohammed.

My question is  (please correct me if I am wrong) - I see the VSAs being returned  during the intermediate Access-Challenge messages too even before  authentication is complete. Is this the normal behavior, is there a way  to setup the freeRADIUS server so that the VSAs are only returned on  Access-Accept and not during the Access-Challenge. The NAS does ignore  the VSAs in any case during the challenge - but would be good if there  was a way to limit the message size for the Access-Challenge messages  (only if this is valid from RADIUS RFC perspective - if someone could

How can I set users in the 'users' file (an example would be very  helpful if someone can send) so that some users are only allowed to  authenticate using EAP-TTLS while others are only allowed to use PEAP.  Once I create an entry into the users file (and both authentications  are EAP types) - the user can authenticate using any eap type - I would  like to limit this per user. Is it possible??
