Barnyard2 webui configuration updates result in ****** written to the config for the password
Any changes to the barnyard configuration page requires that you update the password as well, otherwise ** is written to your configuration and stopping barnyard2 from working properly. I suggest making the password field mandatory on this configuration screen.
Navigate to: https://pfsense/snort/snort_barnyard.php?id=0, hit save, and inspect the newly written baryard2.conf file you will see something like:
output database: log, mysql, user=snort password=******** dbname=snorby host=192.168.x.x
Those *** are where the password should be, that isn't me censoring this bug.
