Hi
I'm looking at implementing a TrustSec SGT policy using ibns 2.0 on some 3650 switches. The policy is intended to apply a "pre-authentication" SGT to clients until they have been authenticated successfully by ISE and has been assigned an SGT by ISE. I setup the following on switches running 03.07.05E.
1 When a session starts, the ibns 2.0 control policy applies a "pre-authentication" SGT tag to the clients traffic. This was done with a locally configured service-template on the switch. Once the client had successfully authenticated, the service-template was deactivated and the client was assigned an SGT from ISE (2.3 patch 5)
policy-map type control subscriber TEST_POLICY
event session-started match-all
10 class always do-until-failure
5 activate service-template PRE-AUTH
10 authenticate using mab priority 10
...
event authentication-success match-all
10 class always do-until-failure
10 deactivate service-template PRE-AUTH
20 authorize
2 As the above worked well, I looked at moving the pre-authentication service-template onto ISE as a downloadable service-template. The ISE authorization profile ISE-PRE-AUTH was configured as a service-template with Access-Reject along with the attributes required to assign an SGT. This also worked as expected
policy-map type control subscriber TEST_POLICY
event session-started match-all
10 class always do-until-failure
5 activate service-template ISE-PRE-AUTH aaa-server ISE
10 authenticate using mab priority 10
...
event authentication-success match-all
10 class always do-until-failure
10 deactivate service-template ISE-PRE-AUTH
20 authorize
3 The problem started when I tried to migrate this setup onto 16.x - I've tried this with 16.3.7 and 16.6.4a
Has anyone come across this issue with ISE downloadable service-templates on 16.x?
Thanks

Just tried version 16.9.2 and the above config works - not sure if this is related to bug CSCvn80164. This is listed as fixed but gives no details of fixed software.
My scenario differs from the bug in that:
