Re: failed admin login attempt NOT recorded in system log

I'm running 4.1.8-1 and attempted login via ssh as 'admin' and 'root' and received syslog for both failed attemps as shown below.

Are you using external authentication profile?  In my testing,  I am only using the local database.  I am not using any external authentication profile.

No auth profile. I'm using the built in administrator 'admin' account in addition to the others listed below.

As you can see, the following is a list of my local users not utilized for administrative logon accounts. Maybe we could take a closer look at your system to see the anomaly first hand?

Re: failed admin login attempt NOT recorded in system log

No auth profile associated with this admin user so to mimic your config, I added the local user 'renato' as an administrator and using the localdb as my auth profile for said user. I still see syslogs for the 'root' user. Only difference I see with our config is that the 'admin' user is configured on my unit whereas it's not on yours.

        }

renato {

        permissions {

          role-based {

            superuser yes;

          }

        }

        authentication-profile LocalDB;

      }

    }

Hmm,  not sure what to say, but I tested with 4.1.7 and 5.0.0 beta.
