ACS certificate issue

[sreejith_r]

I am using peap authentication for wireless. But in ACS its showing NAS error. Then i regenerated the certificate and its started working. But if i restarted the ACS the same thing happening again. Anyone experience this problem before.

Is this autonomous or lwapp? How many ap's or wlc's? Can you post the failed attempt log also.

i am using light weight access points. i dont have the logs right now. once i recreted the certificate the issue will be solved. but that is not a standrd solution. each time we cannot create the certificate.

That isn't how it works. I just installed ACS for one of my clients using PEAP and I have no issues or had ever had issues like what you see. When you make changes in ACS, it will prompt you to restart, which in you case makes PEAP fail. How many WLC's do you have by chance and do you have a backup ACS by chance also?
