Folks,I'm upgrading my test platform of guacamole from 1.4.0 to 1.6.0, native installation on Debian trixie with tomcat 9.0.
Relevant properties used in guacamole.properties are : #mysql-driver: mariadb <= Inactive or not does not matter mysql-hostname: dbserver.example.com mysql-port: 3306 mysql-database: guac-telem mysql-username: <user> mysql-password: <password>I'm using mariadb-java-client-3.5.9.jar connector/J in lib subdirectory (it was 2.7.0 before, and it seems to work with this version)
MariaDB is recognized in the log :2026-06-18 15:40:49,175 [main] INFO o.a.g.auth.mysql.conf.MySQLEnvironment - Installed JDBC driver for MySQL/MariaDB detected as "MariaDB Connector/J"
But JDBC URL is not correct for mariadb anymore :### Cause: java.sql.SQLException: No suitable driver found for jdbc:mysql://dbserver.example.com:3306/guac-telem
I think recent MariaDB Connector/J does not register "mysql" anymore, URL should be jdbc:mariadb://dbserver.example.com:3306/guac-telem instead.
