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).
