Specifying a Dictionary File

The RADIUS server uses a dictionary file to analyze the parameters passed in the request from the NAS. The dictionary file contains RADIUS attribute and value pairs. A number of these attributes are defined in RFC 2138 Remote Authentication Dial In User Service, and RFC 2139 RADIUS Accounting. However, NAS vendors have also defined proprietary attributes.

Do not confuse the RADIUS dictionary file with the RADIUS mapping file which provides a translation between RADIUS attributes and LDAP attributes. For information on the RADIUS mapping file, refer to "RADIUS-to-LDAP Mapping".

Sun Directory Services is provided with a default dictionary that contains the standard attribute and value definitions. It also accepts the dictionaries from the following vendors:

• Livingston

• Ascend

• Cisco

• Shiva

• Bay Networks

The dictionary files provided by vendors contain both standard and proprietary definitions. Attribute and value definitions are identified by an OID which is the actual information passed in a RADIUS transaction. Due to a lack of standardization some proprietary attributes defined by different vendors use the same OID.

The RADIUS server can support any number of dictionary files from different vendors, but you must specify which dictionary to use with a particular NAS.

To Specify a Dictionary File for a NAS

Use the Deja tool to add the dictionaryFile attribute to the directory entry for the NAS.

The value you assign to this attribute must be the filename of the dictionary that the RADIUS server must use for communications with the NAS described by the entry.

If the dictionaryFile attribute is not specified, the default dictionary file is used. This file is located with all other configuration files under /etc/opt/SUNWconn/ldap/current.

If you use the dictionary provided by the NAS vendor instead of the default dictionary provided with Sun Directory Services, you must copy the attributes used internally by the RADIUS server from the default dictionary to the vendor-supplied dictionary. The list of attributes that you must copy is shown in Table 7-1.
