RADIUS attribute from rfc6572
The Mobile-Node-Identifier attribute (Type value 145) is of type
String and contains the mobile node identifier (MN-Identifier), see
, in a form of a Network Access Identifier (NAI) .
This identifier and the identifier used for access authentication may
be different; however, there needs to be a mapping between the two
identities as specified in. This attribute
is used on the interface between the MAG and the AAA server. The
Mobile-Node-Identifier attribute is designed for deployments where
the identity used during network access authentication and the
identity used for mobility management is decoupled. It may also be
the case where the MAG does not have means to find out the MN
identity that could be used in subsequent PBU and Proxy Binding
Acknowledgement (PBA) exchanges (e.g., due to identity hiding during
the network access authentication) or when the HAAA wants to assign
periodically changing identities to the MN.
The Mobile-Node-Identifier attribute MAY be returned by the HAAA in
the RADIUS Access-Accept message that completes a successful
authentication and authorization exchange between the MAG and the
HAAA. The MAG MUST use the received MN-Identifier.
