             Summary: "Communications Link Failure" with AWS Aurora (MySQL)
                 Key: GUACAMOLE-650
                 URL: https://issues.apache.org/jira/browse/GUACAMOLE-650
             Project: Guacamole
          Issue Type: Bug
          Components: guacamole-auth-jdbc, guacamole-auth-jdbc-mysql
    Affects Versions: 0.9.14
            Reporter: Zachary Piazza


I am receiving the following exception when attempting to authenticate against a Aurora RDS cluster. This issue doe not present when authenticating against a standard MySQL server running on an EC2 instance. I have verified that I able able to connect to this endpoint via the mysql command line client as to rule out the possibility of network issues. I have not seen any open issues or discussions on the mailing list regarding this issue. I have tried using the last two version of the mysql-connector with no change. Tried hard coding the "JDBC.loginTimeout" in the auth extension, also with zero impact.

Full stack trace provided here: [http://dpaste.com/0GJ63JE]

I can provide my guacamole.properties configuration if needed, however it is fairly standard, only specifying the guacd hostname and port along with the mysql parameters.
