Authentication session invalidated

k.protopapas — Sun, 10 Mar 2019 22:14:23 GMT

I am getting this message on the ACS 4.1 server failed authentications log.The strange point is that i get thme only for a specific timeframe and then they stop.I am using PEAP-GTC as the authentication method with 1242ABG APs and Intermec CK31 clients.

Hi,

Some questions,

-What is the complete ver of acs software ?

-Which DB you are using here ? like AD/RSA etc

-At the time when this error is seen, do you have Replication or data backup/restore scheduled for that time ?

Regards,

Jagdeep
