This article explains how to add a new Fortinet RADIUS dictionary to RSA RADIUS for RSA Authentication Manager.

The third-party Fortinet device requires a vendor-specific attribute returned in a RADIUS profile returns list.
Resolution

Please contact the vendor of the third-party device or software with regards to the attributes required to be returned in the RADIUS profile.  This information can be used to create a new RADIUS dictionary if the vendor-specific attributes do not already exist. Here is an example of adding a new vendor-specific attribute dictionary to RSA RADIUS for a Fortinet device.

  • The default RSA RADIUS folders for RSA RADIUS 7.1 on Microsoft WIndows is C:\Program Files\RSA Security\RSA Authentication Manager\radius\Service or /usr/local/RSASecurity/RSAAuthenticationManager/radius for Unix and the RSA SecurID Appliance 3.0.
  • For RSA Authentication Manager 8.x, the path is /opt/rsa/am/radius/.
  1. Create a RADIUS dictionary file named fortinet.dct in the RSA RADIUS folder.
  2. Add the following attributes to the new RADIUS dictionary:

@radius.dct

MACRO              FORTINET-VSA(type,syntax)   26   [vid=12356 type1=%type% len1=+2 data=%syntax%]
ATTRIBUTE          Fortinet-Group-Name                                   FORTINET-VSA(1,    string) r
ATTRIBUTE          Fortinet-Client-IP-Address                            FORTINET-VSA(2,    ipaddr) r
ATTRIBUTE          Fortinet-Vdom-Name                                    FORTINET-VSA(3,    string) r
 

Please refer to the readme.dct in the RADIUS folder for detailed information about the dictionary format. 

  1. Update the vendor.ini and add the following new section for the new vendor:
vendor-product  = Fortinet
dictionary       = fortinet
ignore-ports      = no
port-number-usage = per-port-type
help-id           = 2000

NOTE: It is recommended to add the new vendor in alphabetic order as this maintains order in the RADIUS graphical user interface on the pull-down list.

  1. Update a file called dictiona.dcm and add the dictionary filename to the vendor specific list (in alphabetic order):
@fortinet.dct
  1. Stop and start the RSA RADIUS service.
  2. Examine the RADIUS log file (formatted yyyymmdd.log - e.g. 20110829) found in the ../radius folder for any error messages concerning the new RADIUS dictionary (e. g., fortinet.dct).  You are likely to see an update to the dictionary information after adding the new RADIUS dictionary.

  1. When configuring the RADIUS Clients there will be a new Make/model type called Fortinet which will allow vendor-specific attributes to be selected in the Return List of Attributes for RADIUS profiles in the RSA Security Console.
Notes
Contact RSA Customer Support if you still experience a technical issue adding a vendor-specific RADIUS dictionary to RSA RADIUS 6.1 or RSA RADIUS 7.1.
