Hi, Today I did some test with radreply.WISPr-Session-Terminate-Time and radcheck.Expiration. It is supposed both attributes do the same, but Expiration is from AAA server side, meanwhile Session-Terminate-Time is from NAS side. However, there is a difference if you want to to set a username with Session-Timeout (johndoe, Session-Timeout, :=, 3600) since the NAS rewrite the Session-Timeout according to the Date in Session-Terminate-Time. This behaviour does not happen with Expiration attribute. Do you confirm this? _________________________________________________________________ ¿Quieres ver los mejores videos de MSN?
