Resolution

Please perform the following steps to configure RSA RADIUS 6.1 to strip the suffix from the user name:

1) Stop RSA RADIUS process using the RSA Authentication Manager Control Panel

For Windows: RSA Authentication Manager Control Panel > Start & Stop RSA Auth Mgr Services > in Service Management click the Stop RADIUS button

2) Edit the <instdir>\RSA RADIUS\Service\radius.ini file and add the following lines to the bottom of the file:

  [Strip]
  Authentication=Yes
  Accounting=No
  ;StripSuffixCharacters=@
 
  [StripSuffix]
  ; replace the domain suffix below to suit your configuration
  @rsa.com

3) Save the changes to <instdir>\RSA RADIUS\Service\radius.ini

4) Start the RSA RADIUS process using the RSA Authentication Manager Control Panel

For Windows: RSA Authentication Manager Control Panel > Start & Stop RSA Auth Mgr Services > in Service Management click the Start RADIUS button

The RSA RADIUS log (without debugging enabled) will report the following for a valid authentication:

  02/28/2007 12:00:00 Sent accept response for user jsmith to client <radius_client_name>
