Just had the exact same problem with the most current version, but on a Debian server. Spent two hours trying different combinations of all the different things mentioned here on the forums, but alas, no luck. I also got the OperationNotSupportedException a lot when trying to log into the admin panel.
I suspect there might be a simple error in the configuration file. Maybe someone could post his/her complete working wildfire.conf for comparison.
But anyway, for me this would have been a temporary solution anyway, and I kind of decided to do it right from the start now and write my own AuthProvider - hopefully with more success.
I would recommend resetting the conf file to the default and then using the setup tool to set the JDBC values. Once you get that working, you can customize the user provider.
