Description

Hi,

I was trying to set up Guacamole in Kubernetes using both LDAP and MySQL. LDAP users could log in, but guacadmin could not. Manually assigning admin permissions to a LDAP  user via MySQL commands also wouldn't work. I suspected the MySQL connection was not working.

So I looked at the guacamole.properties inside the guacamole container. It contained the line: mysql-port: tcp://<resolved-address-of-mysql-hostname>:3306. 

I had not set the environment variable MYSQL_PORT, because the manual says it defaults to 3306. After I set MYSQL_PORT to 3306, the line in guacamole.properties changed to mysql-port: 3306, and I could log in as guacadmin.

Additional information:

I used guacamole/guacamole:1.3.0. as it was not clear whether the latest tag would provide a recent build of 1.3.0 or a development version.
