I cloned the latest code from master, executed "*docker build -t test/guacamole:1.4.0 .*" to build. Execute "*docker run -v /opt/guacd/record/:/record/ --name guacamole-guacd -d -p 4822:4822 --restart always guacamole/guacd:latest* *docker run -v /etc/localtime:/etc/localtime:ro --name guacamole-guacamole --link guacamole-guacd:guacd -e MYSQL_HOSTNAME=10.0.99.102 -e MYSQL_PORT=3306 -e MYSQL_DATABASE=guacamole_db -e MYSQL_USER= guacamole -e MYSQL_PASSWORD=Guacamole@123 -d -p 8889:8080 --restart always test/guacamole:1.4.0*" to start.
But my page shows error, docker logs shows " *04:02:06.193 [http-nio -8080-exec-8] WARN oageAuthenticationProviderFacade - The "mysql" authentication provider has encountered an internal error which will halt the authentication process.

Maybe there's something wrong with the way I'm building it? Hope to get your help, thank you very much.
