Hey Heitor,
Actually to 1, no they are not. I have mariadb-5.5.41 on the bacula server (client side) and mariadb 10 on the db server. I might try upgrading the client on the bacula server tomorrow. I don't have SELinux enabled anywhere currently. I probably will enable that tho once I get everything working.
I'll try to update you guys tomorrow.
Thanks for all your input!
Tim
