Ubuntu Manpage: dictionary - RADIUS dictionary file

Provided by: freeradius-common_3.0.20+dfsg-3ubuntu0.4_all

NAME

       dictionary - RADIUS dictionary file

DESCRIPTION

       The   master   RADIUS  dictionary  file  resides  in  /etc/freeradius/3.0/dictionary.   It
       references other dictionary files located in /usr/share/freeradius/.  Each dictionary file
       contains  a  list  of  RADIUS  attributes and values, which the server uses to map between
       descriptive names and on-the-wire data.  The names have no meaning outside of  the  RADIUS
       server itself, and are never exchanged between server and clients.

       That  is,  editing  the dictionaries will have NO EFFECT on anything other than the server
       that is reading those files.  Adding new attributes  to  the  dictionaries  will  have  NO
       EFFECT  on  RADIUS  clients,  and  will not make RADIUS clients magically understand those
       attributes.  The dictionaries are solely for  local  administrator  convenience,  and  are
       specific to each version of FreeRADIUS.

       The  dictionaries  in /usr/share SHOULD NOT be edited unless you know exactly what you are
       doing.  Changing them will most likely break your RADIUS deployment.

       If you need to add new attributes, please edit  the  /etc/freeradius/3.0/dictionary  file.
       It's  sole  purpose  is  to  contain  site-local  definitions  that are added by the local
       administrator.

FORMAT

Every line starting with a hash sign ('#') is treated as comment and ignored.

Each line of the file can contain one of the following strings:

ATTRIBUTE name oid type [flags]
Define a RADIUS attribute name to number mapping.

The name field is a printable field, taken from various specifications or vendor
definitions. It is most commonly used as a series of words, separated by hyphens.
e.g. "User-Name". Vendor-specific attributes (VSAs) are prefixed by the vendor name,
e.g. "Cisco-AVPair". The names should be globally unique, as they are used as a key
to look up the properties of the attribute.

The oid field is taken from the relevant specification for that name. In most cases,
it is a decimal number, such as "256". For certain attributes, a "dotted number"
notation is used, e.g. "1.2". The "dotted number" notation is used only for certain
attributes.

The type field can be one of the standard types:

string UTF-8 printable text (the RFCs call this "text")
octets opaque binary data (the RFCs call this "string")
ipaddr IPv4 address
date Seconds since January 1, 1970 (32-bits)
integer 32-bit unsigned integer
ipv6addr IPv6 Address
ipv6prefix IPV6 prefix, with mask
ifid Interface Id (hex:hex:hex:hex)
integer64 64-bit unsigned integer

The type field can be one of the following non-standard types:

ether Ethernet MAC address
abinary Ascend binary filter format
byte 8-bit unsigned integer
short 16-bit unsigned integer
signed 31-bit signed integer (packed into 32-bit field)
tlv Type-Length-Value (allows nested attributes)
ipv4prefix IPv4 Prefix as given in RFC 6572.

The last (optional) field of an attribute definition are additional flags for that
attribute, in a comma-separated list. Previous versions of the server allowed these
flags to include a vendor name. This behavior may still work, but it is deprecated,
and is not recommended.

The options are:

encrypt=# set encryption type 1, 2, or 3.
has_tag The attribute can have an RFC 2868 style tag

The "encrypt" flag marks the attribute as being encrypted with one of three possible
methods. "1" means that the attribute is encrypted with the method as defined in
RFC2865 for the User-Password attribute. "2" means that the password is encrypted
with the method as defined in RFC2868 for the Tunnel-Password attribute. "3" means
that the attribute is encrypted as per Ascend's definitions for the Ascend-Send-
Secret attribute.

The "has_tag" flag marks the attribute as being permitted to have a tag, as defined
in RFC2868. The purpose of the tag is to allow grouping of attributes for tunneled
users. See RFC2868 for more details.

When the server receives an encoded attribute in a RADIUS packet, it looks up that
attribute by number in the dictionary, and uses the definition found there for
printing diagnostic and log messages. When the server sees an attribute name in a
configuration file, it looks up that attribute by name in the dictionary, and uses
the definition found there.

VALUE attribute-name value-name number
Define an attribute value name to number mapping, for an attribute of type integer.
The attribute-name field MUST be previously defined by an ATTRIBUTE entry. The
value-name field can be any non-space text, but is usually taken from RFC2865, or
other documents.. The number field is also taken from the relevant documents, for
that name.

When the server receives an encoded value in a RADIUS packet, it looks up the value
of that attribute by number in the dictionary, and uses the name found there for
printing diagnostic and log messages.

VENDOR vendor-name number [format=...]
Define a Vendor Specific Attribute encapsulation for vendor-name to number. For a
list of vendor names and numbers, see http://www.iana.org/enterprise-numbers.txt.

The "format=t,l" statement tells the server how many octets to use to encode/decode
the vendor "type" and "length" fields in the attributes. The default is
"format=1,1", which does not have to be specified. For USR VSA's, the format is
"format=4,0", for Lucent VSA's it's "format=2,1", and for Starent VSA's it's
"format=2,2".

The supported values for the number of type octets (i.e. the first digit) are 1, 2,
and 4. The support values for the number of length octets (i.e. the second digit)
are 0, 1, and 2. Any combination of those values will work.

BEGIN-VENDOR vendor-name
Define the start of a block of Vendor-Specific attributes. All of the following
ATTRIBUTE definitions are interpreted as being for the named vendor, until the block
is closed by an "END-VENDOR" statement.

This practice is preferred to placing the vendor name at the end of an ATTRIBUTE
definition.

For VSAs in the RFC 6929 "Extended vendor-specific" space, a format can be specified
following the "vendor-name". The format should be "format=Extended-Vendor-
Specific-1", through "format=Extended-Vendor-Specific-6". The matching "END-VENDOR"
should just have the "vendor-name", without the format string.

END-VENDOR vendor-name
End a previously defined BEGIN-VENDOR block. The "vendor-name" must match.

$INCLUDE filename
Include dictionary entries from the file filename. The filename is taken as relative
to the location of the file which is asking for the inclusion.

BEGIN-TLV name
This feature is supported for backwards compatibility with older dictionaries. It
should not be used. The new "oid" form for defining the attribute number should be
used instead.

END-TLV name
This feature is supported for backwards compatibility with older dictionaries. It
should not be used. The new "oid" form for defining the attribute number should be
used instead.
