Authorize Only. In addition to the Service-Type attribute, the CoA-Request
includes session identification attributes, a State attribute, and NAS
identification attributes. The CoA-Request does not contain any other
attribute.
2. If the NAS supports the Authorize Only mode, it responds with a CoA-NAK
containing the Service-Type and Error-Cause attributes. The value of the
Service-Type attribute is Authorize Only and the value of the Error-Cause
attribute is Request Initiated.
3. Subsequently, the NAS sends an Access-Request to the HP-UX AAA Server,
including a Service-Type attribute and the State attribute that was sent by
the HP-UX AAA Server in the initial CoA-Request. The value of the
Service-Type attribute is Authorize Only.
4. The HP-UX AAA Server responds to the Access-Request with an
Access-Accept to reauthorize the session or an Access-Reject to disconnect
it.
Configuring for Dynamic Authorization in Authorize Only Mode
To configure the HP-UX AAA Server for dynamic authorization in the Authorize Only
mode, complete the following steps:
1. To configure the HP-UX AAA Server to send Disconnect and CoA requests in
the default mode, complete the procedure described in the following files:
For Oracle — /opt/aaa/examples/sqlaccess/oracle-1/README
For MySQL — /opt/aaa/examples/sqlaccess/mysql-1/README
2. Modify the /etc/opt/aaa/client-request-init.grp file as follows:
For Authorize Only mode, the RADIUS message type for both Disconnect
and CoA requests must be CoA-Request. Therefore, replace the following
lines:
## Set the RADIUS message type of the request to Disconnect-Request.
insert Interlink-Packet-Code = "Disconnect-Request"
with
## Set the RADIUS message type of the request to COA-Request.
insert Interlink-Packet-Code = "COA-Request"
Insert a Service-Type attribute. Assign Authorize-Only as the value of
the attribute. Append the following lines at the end of the /etc/opt/aaa/
client-request-init.grp file:
## Add Service-Type attribute with value "Authorize Only"
insert Service-Type = "Authorize-Only"
3. A CoA-Request, whose Service-Type attribute value is Authorize Only,
must include session and NAS identification attributes only. Therefore, the
Filter-Id attribute must be removed from the Change-Of-Authorization request.
