So the contens of the /lib and /extensions folder are the following: /lib: mysql-connector-j-9.5.0.jar
/extensions: guacamole-auth-jdbc-mysql-1.6.0.jar So i assume i am missing something, correct? and where can i get the missing files? In the future i want to work with ldap but i guess i can add the files then right? Thanks Felix Am Mi., 19.
