This clause authenticates users from a local or remote SafeWord
               PremierAccess (SPA) server. SafeWord PremierAccess and tokens are
               available in 
Secure
                  Computing website 
. It supports PAP, CHAP, TTLS-PAP, EAP-OTP and
               EAP-GTC. It supports password changing, fixed (static) passwords and Safe-
               Word Silver and Gold tokens.
Only the first authenticator configured into SPA for the user will be
               used by Radiator to authenticate the user. The second and subsequent
               authenticators configured for a user will be ignored.
            
               Note
               In order to support CHAP, the user must have a fixed password
                  profile with ‘case sensitive password’ enabled in the SafeWord
                  server.
             
            
               Note
               A user can changed their fixed password at any time by entering
                  their current and new passwords in a special format. The password change
                  will only succeed if the old password is correct, and the two copies of
                  the new password are identical and conform to the password length and
                  other constraints configured into SPA for the user's fixed password
                  authenticator.
