Running RADIUS in permanent debug mode with rotating log

[Clement Ogedengbe]

One of our radius servers started acting strange and there has been no config change except that we updated the DELL hardware storage firmware of the server.

MSCHAP authentication request returns Access-Accept, but the client does not get authenticated. We have two servers with similar config. Authentication request sent to the other server is OK. I ant figure out what the issue is.

Extract of log below:
