I got many Cisco AP which are linked to 2 Cisco WLC.
On each WLC, I configured a primary and a secondary RADIUS Server.
RADIUS servers are Cisco ACS 188.8.131.52 (patch 10)
Primary and secondary ACS configurations are synchronized.
There are no problem between primary WLC and Cisco ACS (primary and secondary).
When secondary WLC requests primary Cisco ACS, I get this error "11036 The Message-Authenticator RADIUS attribute is invalid"
Secondary WLC automatically contacts secondary Cisco ACS and it works fine.
Cisco ACS description for this error: "This maybe because of mismatched Shared Secrets."
The two Cisco ACS are synchronized so I should have same error on them...
Why does primary ACS generate this error?
Thanks for your help,
