7.6(120.0) 8.3(15.158)

Description (partial)

Symptom:
config guide and TAC NPI all declare that DNS based ACL will work on flex local switching (with central auth). This is not true.
From a conceptual perspective already, with flex, you need to configure a Flex ACL as redirect-ACL since 7.5. So how is the WLC supposed to know which FQDN ACL to pull since the FQDN ACLs are configured with regular ACLs and not with flex ACLs ... ?

As a matter of fact, both customers and TAC are reporting that it just doesn't work. The same setup will work perfect if setting the AP back to local mode.

Conditions:
WLC 7.6
DNS based ACLs
Flexconnect local switching, central auth.
Flexconnect Central switching,central auth with regular ACL (broken too)
