Abstract
This document describes the set of Microsoft vendor-specific RADIUS
attributes. These attributes are designed to support Microsoft
proprietary dial-up protocols and/or provide support for features
which is not provided by the standard RADIUS attribute set [3]. It
is expected that this memo will be updated whenever Microsoft defines
a new vendor-specific attribute, since its primary purpose is to
provide an open, easily accessible reference for third-parties
wishing to interoperate with Microsoft products.
1. Specification of Requirements
In this document, the key words "MAY", "MUST, "MUST NOT", "optional",
"recommended", "SHOULD", and "SHOULD NOT" are to be interpreted as
described in [2].
2. Attributes
The following sections describe sub-attributes which may be
transmitted in one or more RADIUS attributes of type Vendor-Specific
[3]. More than one sub-attribute MAY be transmitted in a single
Vendor-Specific Attribute; if this is done, the sub-attributes SHOULD
be packed as a sequence of Vendor-Type/Vendor-Length/Value triples
following the inital Type, Length and Vendor-ID fields. The Length
field of the Vendor-Specific Attribute MUST be set equal to the sum
of the Vendor-Length fields of the sub-attributes contained in the
Vendor-Specific Attribute, plus six. The Vendor-ID field of the
Vendor-Specific Attribute(s) MUST be set to decimal 311 (Microsoft).
